IB Math AA or AI for Medicine, and AP Precalculus in 10th
Your 9th grader is in Algebra 2 at an AP/IB school. The plan is Advanced Placement (AP) Precalculus in 10th grade, then International Baccalaureate (IB) math at standard level in 11th and 12th, and she wants medicine or nursing.
Your 9th grader is in Algebra 2 at an AP/IB school. The plan is Advanced Placement (AP) Precalculus in 10th grade, then International Baccalaureate (IB) math at standard level in 11th and 12th, and she wants medicine or nursing. Here is what the sources print about that math thread.
The College Board's prerequisite line for AP Precalculus names "introductory algebra and geometry courses" and then a list of skills; it does not name Algebra 2. The IB offers two math courses, analysis and approaches (AA) and applications and interpretation (AI), each at standard level (SL) and higher level (HL), and "Students can only study one course in mathematics as part of their diploma." Both carry calculus; AA carries more of it, AI more statistics.
Of seven medical school pages read on November 5, 2026, none makes calculus a course requirement for its main MD path, and none names an IB course. Statistics is the math named most often. Where the AA-or-AI and SL-or-HL choices bite is college credit: the University of California credits AA at Higher Level only and gives no credit for AI, while the University of Washington credits both courses at both levels.
AP Precalculus in 10th grade after Algebra 2 in 9th
The College Board's recommended prerequisites for AP Precalculus, in full: "You should have successfully completed introductory algebra and geometry courses. In particular, you should be able to demonstrate proficiency with linear functions, polynomial addition and multiplication, factoring quadratic trinomials, using the quadratic formula, solving right triangle problems involving trigonometry, solving linear and quadratic equations and inequalities, algebraic manipulation of linear equations and expressions, and solving systems of equations in two and three variables. You should also be familiar with piecewise-defined functions, exponential functions and rules for exponents, radicals (e.g., square roots, cube roots), and complex numbers."
That is a list of skills, not a course name. Her Algebra 2 syllabus is where to check it, item by item, with her teacher. Whether she takes the AP Precalculus exam at the end is a separate question, on our AP Precalculus without the exam page.
The IB's two math courses, at SL and HL
The IB's mathematics page lists four options: Mathematics: analysis and approaches at SL and at HL, and Mathematics: applications and interpretation at SL and at HL. Two courses, each at two levels; a student takes one. The curriculum is changing. The IB page says, "The final assessment of these courses is November 2028. A new curriculum will be taught from 2027," and each new course has a brief marked first assessment 2029. A 9th grader this year reaches the two IB years in fall 2028 and takes her IB exams in 2030, so the new briefs are the ones that apply to her. On levels, the briefs say: "Normally, three subjects (and not more than four) are taken at higher level (HL), and the others are taken at standard level (SL). The IB recommends 240 teaching hours for HL subjects and 150 hours for SL."
| Course | What the brief says it centers on | Calculus hours | Probability and statistics hours |
|---|---|---|---|
| AA SL | "a specific focus on mathematical analysis using functions and calculus" | 30 of 150 | 22 of 150 |
| AA HL | the same sentence | 59 of 240 | 28 of 240 |
| AI SL | "a specific focus on mathematical modelling and statistical analysis and includes the study of functions and calculus" | 19 of 150 | 36 of 150 |
| AI HL | the same sentence | 41 of 240 | 52 of 240 |
AA or AI, for her
None of the seven medical school pages read for this page names an IB course. The word they use is statistics, and AI SL gives it 36 hours against AA SL's 22. Both courses carry calculus, AA SL 30 hours against AI SL's 19. Where the choice bites is college credit. The University of California's IB credit page carries analysis and approaches on its list and says "No credit is awarded for the Mathematics Applications and Interpretations exam offered 2021 and later," and it speaks of Higher Level exams only. The University of Washington says, "In most cases, credits are awarded for subjects in which the student has earned a grade of 4 or higher," and its table credits both courses at SL and at HL: analysis and approaches at SL from a 4, applications and interpretation at SL from a 5. So her college list decides, and that is question 4 for the IB coordinator below.
What medical school pages print about math
Most of these pages speak of college coursework. Where high school work counts at all, it is as AP or IB credit on a college transcript. Here is what each school's own page printed when we read it on November 5, 2026. Harvard's is a saved copy dated February 10, 2026, because the live page did not open.
| School | The math line | The AP or IB line |
|---|---|---|
| Yale School of Medicine | Biostatistics or statistics, one semester, recommended but not required now; "In the 2027-28 application year, all applicants are required to complete a half year of biostatistics or statistics (1 semester)." | "U.S. Advanced Placement credits or International Baccalaureate credits satisfy the premedical requirements, so long as your primary undergraduate institution gave you credit on an institutional transcript." |
| Harvard Medical School | "Pathways applicants are encouraged to complete a one-year mathematics sequence that includes calculus and statistics, preferably biostatistics." Its separate HST track prints that "HST candidates are required to demonstrate competency in upper-level mathematics, biochemistry, molecular biology, and calculus-based physics." | "We will only accept AP credits if students scored a 4 or 5 on the respective AP test." Harvard does not let AP credit count toward biology or writing. |
| Penn (Perelman School of Medicine) | "No specific courses are required; however, competency in biology, chemistry, physics, biochemistry, and mathematics must be demonstrated." | To the question whether AP or IB credits are accepted: "Yes, if visible on your transcripts. Students are encouraged to take the next sequential course to demonstrate full competency of material." |
| Duke University School of Medicine | Duke's listed courses are "not required"; on statistics, "An understanding of the application of statistical methods in the analysis of data is expected." | "In addition, we will consider AP coursework if approved by your undergraduate institution." |
| Northwestern University Feinberg School of Medicine | "We also recommend courses in statistics, writing and social sciences." | Science AP courses credited by the college "will be considered," and the committee "will expect to see an advanced level undergraduate course in the science discipline for which the AP credit was awarded." |
Stanford and NYU, read the same day, print no course requirements. Stanford's page says, "Applicants must be able to apply quantitative reasoning, statistical principles, and appropriate mathematics to describe or explain phenomena in the natural world and evaluate the published scientific literature." NYU Grossman "does not have prerequisites" and recommends a short list of premedical courses, one of them statistics. Yale's 2027-28 rule starts years before a 9th grader today would apply.
What two nursing pages print
The University of Texas at Austin's page for its Bachelor of Science in Nursing (BSN) says, for students who transfer in from another college: "There are three pre-requisite courses needed: Biology, Chemistry, and Statistics. These are introductory level courses, not requiring labs." The University of Washington's BSN takes a student in as a college junior with prerequisite courses that include statistics, and on AP and IB it says, "AP and IB credit may be accepted under the University's standard guidelines." Both pages speak of college courses; neither names a high school math course.
What to ask the school's IB coordinator
- Which of the four IB mathematics options the school teaches, and at which level. The IB lists four; the school's list is the one she can take.
- Whether her 11th-grade course is the new curriculum, the one first examined in 2029.
- Whether AP Calculus AB can fit in 12th grade beside the diploma. The College Board's line for it: "You should have successfully completed courses in which you studied algebra, geometry, trigonometry, analytic geometry, and elementary functions."
- For each college on her list: its IB credit page, and whether it credits SL exams, HL exams, or both.

FAQs
Can a 10th grader take AP Precalculus after Algebra 2 in 9th grade?
The College Board sets no grade and no course name. Its prerequisite line asks for "introductory algebra and geometry courses" and a list of skills. If her Algebra 2 course covers that list, she meets the line as printed. The school decides placement.
IB math AA or AI for medicine?
None of the seven medical school pages we read names an IB course; they name college coursework, and statistics most often. AI SL carries more statistics hours (36 against 22) and AA SL more calculus hours (30 against 19). On credit, the University of California credits analysis and approaches at Higher Level and gives "No credit" for applications and interpretations; the University of Washington credits both courses at SL and HL. Her college list decides.
Is IB math SL enough for medicine, or does she need HL?
No medical school page we read names an IB level. Where the level matters is college credit: the University of California's IB page speaks of Higher Level exams only, while the University of Washington credits SL exams too, analysis and approaches from a 4 and applications and interpretation from a 5. The IB itself says normally three subjects, "not more than four," are taken at HL, so math at SL leaves the HL slots for other subjects.
Does medical school require calculus?
Not as a course requirement on any of the seven main MD pages read on November 5, 2026. Harvard's page says a one-year sequence "that includes calculus and statistics" is "encouraged," and its separate HST track requires "competency in upper-level mathematics" and "calculus-based physics." Stanford asks for "quantitative reasoning, statistical principles, and appropriate mathematics." NYU recommends statistics. Yale, Duke, and Northwestern name statistics; Penn names mathematics.
Do I need AP Calculus for pre-med?
No page we read asks for it. Where AP counts on these pages, it is as college credit on the transcript: Yale and Penn accept AP or IB credit that way, Harvard accepts an AP score of 4 or 5, Duke "if approved by your undergraduate institution," and Northwestern with an advanced course expected in that subject. Whether AP Calculus AB fits in 12th grade beside the diploma is question 3 for the IB coordinator above.
What math do nursing programs want?
Statistics, on both pages we read, as a college course. The University of Texas at Austin names "Biology, Chemistry, and Statistics" as its three prerequisites for transfer applicants, and the University of Washington's BSN prerequisites include statistics. Neither names a high school math course.
AP Physics 1 in 10th grade: what math does it use?
Geometry done, and Algebra 2 alongside. The College Board's line: "You should have completed a geometry course and be concurrently taking Algebra II or an equivalent course." Her Algebra 2 year in 9th is the Algebra II that line names; the geometry course is the one to confirm. The math each physics course uses, by course, is on our 9th grade physics page.
