Meet your Grade 10 biology tutors
What these three have in common is not a teaching qualification. It is that all of them scored at the top of AP Biology and then went and used it: two are in research labs right now, and one has spent five years as a teaching assistant and tutor while doing the same. That matters in grade 10, because the year is about applying mechanisms rather than reciting them.
Explore all our Biology Tutors
Every tutor on our platform has been through a credential verification process. You can browse and filter by subject and grade level on the full tutors directory.
The year memorising stops working
Ninth grade biology rewards a good memory. Learn the organelles, label the diagram, name the stages of mitosis, get the A. Plenty of students build their whole method on that, and through 9th grade biology it holds up fine.
Grade 10 breaks it. The questions stop asking what happens and start asking what would happen if, and they attach a graph the student has never seen. A student who can recite the stages of meiosis is still stuck when the question gives a pedigree and asks which parent carried the allele. Nothing has been forgotten. The method just ran out of road.
Parents usually read this as effort dropping off, because the child is studying the same way for longer and getting less back. It is almost never effort. It is that flashcards cannot practise reasoning, and reasoning is what is now being marked.
What a 10th grade biology tutor actually works on
Sessions follow the student's own syllabus and their own assessment calendar. Across US and Canadian grade 10 biology courses that usually means:
Cell structure and function. Organelles as a system with a job rather than a labelled diagram. Our free cell structure cheat sheet was written for AP Biology and overlaps almost entirely with what grade 10 covers.
Cellular energetics. Photosynthesis and respiration as two halves of one process, which is the framing that makes both stick. The cellular energetics cheat sheet is the fastest way to see whether the gap is biology or the chemistry underneath it.
Genetics and heredity. Punnett squares, non-Mendelian patterns, and pedigree analysis, built around the heredity performance expectations that most state frameworks use, including the standard on applying statistics and probability that catches students out. The heredity cheat sheet walks through chi-square testing specifically.
DNA, protein synthesis, and gene expression. Transcription and translation, and why a single base change matters. The gene expression cheat sheet covers the regulation content that grade 10 usually introduces and grade 11 finishes.
Evolution and natural selection, where the marks come from explaining a mechanism, not from defining a term.
Ecology and ecosystems, usually the unit carrying the most data interpretation and the most graphs.
Lab skills and data questions. Controls and variables, reading a graph, and writing a claim supported by evidence. The AP Biology labs guide is the closest thing we publish to a grade 10 lab skills reference, and the biology formula sheet collects the calculations that turn up in data questions.
Not included: writing lab reports for the student, completing take-home assessments, or supervising science fair projects. Tutors will teach the biology behind a lab and talk through how to structure the write-up. They will not produce the submission.
Students carrying two sciences in the same year often run one package across both, pairing this with grade 10 chemistry tutoring, since the cellular energetics unit leans on chemistry the student may not have met yet. Anyone sitting AP Biology early should start from the AP Biology resource hub, which has the free unit cheat sheets and the formula sheet.
Isaac Yang has tutored biology and chemistry for five years, holds a 1560 SAT and a 35 ACT, and now runs research in UIUC's Shen Lab while working as a teaching assistant in the accelerated chemistry lab course. He sees the same material from three sides in a normal week: as a researcher, as a lab TA marking work, and as a tutor. That is a useful vantage point for the question every parent asks first, which is why a hardworking student's grade dropped.
You tell us the course and the unit.
Not "he needs biology help", but "honors biology, the genetics test came back at 68, the ecology unit starts in three weeks." Course name, textbook, and the next assessment date are the three details that make a real match possible.
2
A person picks the tutor.
Biology is broad enough that the match matters: a tutor strong on genetics and molecular work is not automatically the right one for an ecology-heavy course. You get a name and a profile link before anything is booked, which is the same standard the whole tutor directory is built on.
3
The $50 diagnostic hour.
Sixty minutes, one-on-one, spent finding whether the student is losing marks on recall, on applying a mechanism, or on reading data. Those need different work. It ends with a written plan and a feedback summary, and if you upgrade to a package within 48 hours the $50 comes off it.
4
Personalized sessions with progress reports.
Based on the diagnostic, the tutor builds a session-by-session plan. Your child gets bi-weekly progress updates. If the match is not right, we change it for free.
Where grade 10 biology sits in the four-year science sequence
Biology in grade 10 is rarely a standalone problem. It sits in the middle of a four-year sequence, it runs alongside two or three other courses that feed it, and the mark it produces decides what a student is allowed to take next. Knowing where the pressure is actually coming from is usually half the diagnosis.
What came before it
Most sophomores arrive from either a dedicated biology year or a general science year. A student who came through a full grade 9 biology year usually has the vocabulary and has simply never been asked to apply it, which is a narrow and fixable gap. A student who came through an integrated science year will need longer on the cell units, because the chemistry underneath them was covered lightly or not at all. That is why students who found 9th grade chemistry hard tend to hit the same wall again in cellular energetics, and it is worth fixing once rather than twice.
Algebra matters more here than families expect. The probability and statistics work in the genetics unit assumes fluency that 9th grade math was supposed to build, and a student who is shaky there will read a chi-square question as a biology problem they cannot do.
Graph reading is the other inherited skill. Students who took 9th grade physics met that habit a year early, which shows up immediately in how they handle a biology lab write-up.
If more than one subject went badly last year, the grade 9 program is the better place to start than any single course page. It also covers the grade 9 electives and humanities, which is where a timetable problem often hides.
What is running alongside it this year
Very few sophomores take biology on its own. Most are carrying 10th grade chemistry or 10th grade physics in the same year, and one of those is usually the course actually eating the study time. Chemistry is the closer of the two: photosynthesis and respiration are chemistry problems that happen to be set inside a cell, so a chemistry gap shows up as a biology grade.
Then there is the maths. 10th grade math, whether that is Algebra II or Geometry, is doing quiet damage to biology marks the moment the heredity unit starts. A chi-square question in a genetics test is a maths question wearing a biology costume, and students lose those marks without ever realising the biology was fine. Running both subjects with one tutor is common for exactly this reason.
Outside the sciences, the full grade 10 subject list covers English II, US History, languages, computer science, and the electives. If more than one subject is slipping at once, the grade 10 hub is the better starting point than any single subject page, because the problem is usually workload management rather than any one course.
What it decides for grades 11 and 12
This is the part that makes grade 10 matter more than its own transcript line suggests. The grade 10 biology result is a major input into whether a student is placed into honors or AP science the following year.
Students who hold the foundation move into 11th grade biology or straight into AP Biology with room to spare. Students who do not spend grade 11 patching a foundation while also meeting harder material, which is the worst possible year to be doing both.
Junior year also rarely comes alone. Most of those students are carrying 11th grade chemistry in the same timetable, and a smaller group adds 11th grade physics on top of it.
The maths steps up at the same time, since 11th grade math moves into pre-calculus for most students just as formal test prep begins.
The grade 11 hub maps that year in full, including the electives and humanities subjects that quietly eat the study hours.
By senior year the work has changed character again. 12th grade biology is closer to a first-year university course than to anything a sophomore has seen.
Students heading for a science or pre-med major usually run 12th grade chemistry beside it, and the engineering-bound add 12th grade physics. Underneath both sits 12th grade math at calculus level, which is where the workload actually breaks people.
The grade 12 hub covers the final year including its electives and humanities. The whole four-year path sits on the high school tutoring hub, which is the right link to send a parent who is planning rather than firefighting.
What sessions actually look like
Every session is online, private, one-on-one, and 60 minutes, on a shared whiteboard, because biology at this level is drawn as much as it is discussed. Pedigrees, energy pathways, and food webs all need to be sketched while the student watches, then sketched again by the student. The tutor also works from the student's own textbook and the teacher's own slides.
What you supply is short: the course name or syllabus, the last two graded assessments, and the dates of the next two. The marked work is the important part. A tutor can read a returned biology test in a few minutes and tell whether the student is losing points on recall, on application, or on data questions, and those three problems have nothing in common.
Between sessions students get targeted practice rather than a chapter to reread. Six pedigree problems chosen against one weakness beats forty flashcards chosen against a unit.
Where a student needs two sciences held together, the same session can cover both. Several people on the chemistry tutor roster also teach biology, and the crossover matters most in the cellular energetics unit where the two courses genuinely overlap.
What 10th grade biology tutoring costs
A first session runs 60 minutes and costs $50. After that, the published high school rates are package based: 15 lessons at $915, which is $61 per lesson, or 20 lessons at $1,180, which is $59 per lesson. Upgrade within 48 hours of the diagnostic and the $50 is credited toward the package.
Package length is what moves the number. The subject does not, and neither does the tutor's university, so a student running biology and chemistry together pays the same per lesson as one running biology alone.
For context on what you will see elsewhere: marketplace tutors advertise from around $20 an hour with no screening standard behind the listing, most of the large biology tutoring brands publish no rate at all on their subject pages, and subscription platforms run from roughly $30 to $235 a month for library access rather than one-to-one time. Those are three different products, and the comparison below is the honest version.
What grade 10 biology has to do with the SAT and ACT
More than most families realise, and the connection is worth understanding in grade 10 rather than discovering it in grade 11.
The ACT science section tests almost no memorised science. It hands students experimental setups, graphs, and tables they have never seen and asks them to read the data, compare two competing hypotheses, and work out what an experiment actually controlled for. That is the identical skill grade 10 biology labs are built to develop. A sophomore who gets genuinely good at biology data questions is doing early ACT preparation without anyone calling it that.
When the formal work does start, usually in grade 11, the ACT tutor roster is staffed by people who scored 34 to 36 themselves, which matters more on the ACT than on any other test because the section is as much about pacing as comprehension.
The SAT works differently. It has no science section at all, but its reading passages lean heavily on science writing, and its data-interpretation questions reward the same habit of reading a figure before reading the answer options.
Most families begin one-to-one SAT work in grade 11, which makes grade 10 the year the runway gets built rather than used. The PSAT in the autumn of junior year is the one that decides National Merit eligibility, and it arrives sooner than parents expect.
If you have not yet decided which test to aim at, do not decide in grade 10. Our SAT and ACT comparison sets out the honest differences, and the ACT science section guide covers what changed recently, which matters because the answer for a strong biology student is not always the obvious one.
Kurtis Lee, on the roster above, scored a 36 on the ACT and a 1570 on the SAT alongside his AP Biology work. That combination is not a coincidence. The students who read data well tend to do it in every subject at once.
How to choose a Grade 10 biology tutor
Six things worth checking before you pay anyone, us included.
Can you see who will teach, before you book? A stock photo and a first name is not a credential. A profile page naming a university, a degree, and a score is.
Has the tutor actually done well in this subject recently? Biology moves. Someone who scored top marks in AP Biology in the last few years and now works in a lab is closer to the current material than a generalist who covers eight subjects.
Does the tutor match the unit, not just the subject? Genetics, ecology, and molecular biology reward different strengths. Ask which units they have taught this year.
How fast can they start, and does it matter? A marketplace tutor starts tonight; a vetted match takes a few days. If the test is Thursday, the honest answer is that the marketplace may serve you better this week.
What happens when the match is wrong? Ask before you book. Refunds, credits, and swapping tutors are three separate things and providers often blur them.
Do they hold a teaching qualification? The tutors here are subject specialists with strong university records rather than licensed classroom teachers. Where a student has an IEP or a diagnosed learning difference, a provider staffed by certified teachers is usually the better choice, and that is what we will say on the first call.
Numbers 4 and 6 are the two where another provider often wins outright. They are on the list because a test you cannot fail is not a test.
Prisha Bali studies Bioengineering at UCLA and scored a 35 on the ACT along with top marks in AP Biology, AP Chemistry, and AP Calculus BC. Her research is on injectable hydrogels for dental implant healing, and she designs and teaches STEM activities aimed at getting more girls into engineering. She therefore spends real time teaching this material to people meeting it for the first time, which is a different skill from knowing it.
Grade 10 biology help, five options compared
Two of those rows are not us and one of them is free. If your child has a single confused topic and a teacher who runs office hours, start there and keep your money.
Who this is right for, and who it is not
A good fit when:
The grade is sliding across a whole unit, not on one bad test
The student studies hard, studies the same way as last year, and is getting less back for it
Honors or AP Biology in grade 11 is the goal, and the foundation needs to hold
Biology and chemistry are both being carried this year and one is dragging the other
The family wants the tutor's name, university, and scores before paying
Not a good fit when:
The test is in three days and nothing has been started. A few sessions will not rebuild a unit that fast.
The student needs formal accommodation or an IEP-aligned approach. A certified teacher service is the better call.
Nobody has asked the student whether they want help. Tutoring a student who has not agreed to it wastes your money and their evening.
What is actually wanted is homework completion. That is not what these tutors do.
If your 10th grader is aiming at AP Biology
Sophomores sitting AP Biology early are a real group, and they need different work from everyone else on this page. The course assumes a full year of introductory biology and a full year of chemistry behind it. The students who struggle are almost always the ones who took biology in grade 9 and are sitting chemistry at the same time rather than having finished it, because the biochemistry in the opening units lands without a foundation.
Start with the free material before paying anyone. The AP Biology resource hub indexes cheat sheets for all eight units plus a one-page formula sheet, at no cost and behind no signup.
Read the chemistry of life cheat sheet first. Unit 1 is precisely where a sophomore without a chemistry year gets caught, and it is diagnostic: if that unit feels foreign, the problem is chemistry, and the AP Chemistry resource hub covers the same ground from the other side.
When self-study stops being enough, NAT's AP tutoring covers every AP subject on the roster, and several of the biology tutors teach AP Chemistry alongside it. For the smaller group already looking seriously at medicine, the MCAT program is staffed by tutors who came up through this exact sequence. That is worth knowing in grade 10 for one reason only: it shows the path is continuous rather than a series of unrelated hurdles, and the study habits built now are the ones being used in eight years.
What we can show you, and what we cannot
Here is the evidence and its limits. Every tutor named on this page has a profile you can open right now, and the credentials are checkable: a 1560 SAT with five years of biology and chemistry tutoring, a UCLA bioengineering researcher with top AP Biology and AP Chemistry scores, and a 36 ACT with 15 AP courses scored at 4 or 5. At company level, North American Tutors publishes four figures: 59,950+ lessons, 4,950+ students, 30+ countries, and 92 percent of students gaining two or more letter grades or 90 or more SAT points.
What sits behind that 92 percent is not published: no cohort size, no window, no method. It is a first-party claim and should be read as one.
What does not exist yet is a biology case study. The published student case studies are real, detailed, and worth reading, and every single one is SAT, ACT, or MCAT. There is no third-party review platform rating either, which is why no star ratings appear anywhere on this page. When a grade 10 biology result is documented properly, with permission, it will be published here.
Preparing for the SAT and ACT with a 10th grade math foundation
10th grade is also the year many students take the PSAT and when families start thinking seriously about the SAT and ACT timeline. The math foundation built in 10th grade directly affects every standardized test score.
The digital SAT has 44 Math questions across two adaptive modules. The ACT has 60 Math questions in 60 minutes. Both tests draw heavily on content that appears in 10th grade coursework.
For students who want to start SAT Math prep while reinforcing their 10th grade curriculum, there's genuine overlap. The SAT vs. ACT comparison guide helps families decide which test to prioritize. The digital SAT score calculatortranslates a current practice score into a target gap.
As practical study resources, the SAT math formula sheet and the ACT math formula sheet both show exactly which formulas appear on each test. Most of them are 10th grade content.
Students targeting top colleges should know that the Ivy League SAT score requirements consistently sit at 1500 or above, which requires a near-perfect SAT Math performance. A student with a strong 10th grade math foundation has more time to build their test-taking strategy on top of the content they already know, rather than learning both content and strategy simultaneously under time pressure.
