About the course
AP Pre-Calculus for 10th–12th graders aiming at AP Calculus AB or BC. We cover function families, exponentials and logs, trigonometry and trig identities, sequences and series, and the AP Pre-Calculus framework — aligned to your child's school syllabus with free-response drills. The goal is the calculus foundations that actually matter, taught with rigor.
A typical class
Every AP Pre-Calculus class follows the same structure so students walk in knowing what to expect and walk out with a corrected mini-quiz in hand.
Warm-up with logic puzzles, math riddles, and short brain-teaser problems. The point is to switch the brain on without yet introducing today’s topic — students arrive at different focus levels and this 30-minute block evens the room.
First half of today’s topic. One AP Pre-Calc topic per meeting — function families, exponentials and logs, trigonometry, identities, or sequences. Concept-first: the instructor demonstrates one or two worked examples, then students try guided practice with the teacher walking the table.
A short break — water, stretch, a quick chat. Five minutes is enough to reset focus without losing the rhythm of the class.
Second half of the topic, focused on word problems, abstraction, and math applied to real situations. Examples we use: Modeling daily sunlight in NYC across the year (a real sinusoid); compound interest with continuous compounding (the role of e); population growth as exponential vs. logistic models.
A short timed mini-quiz on today’s topic, then we correct it together — question by question, out loud, with the right strategy spelled out for each item. Parents get the corrected paper at the end of the session so they know exactly where their child stands.
Independent topic rotation
Each class is an independent, self-contained topic. When enrollment is open, students can join any week at the appropriate course level; earlier-numbered classes are not required. Every meeting introduces the ideas needed for its topic, with guided practice, support, and challenge options. Class numbers identify sessions in the rolling rotation, not prerequisites or a required order.
Students in grades 10–12 taking AP Precalculus or traditional Precalculus, students who need to strengthen Algebra 2 foundations, and students preparing for Calculus. Placement depends on demonstrated readiness, not just grade level.
Classes meet at 226 W 79th St, 1st Floor, New York, NY 10024. Review the current schedule, or call (646) 668-6151. Start with a free 30-minute evaluation and a written diagnostic within 48 hours.
AP exam preparation focuses on polynomial and rational functions, exponential and logarithmic functions, and trigonometric and polar functions. College Board assesses Units 1–3; Unit 4, involving parameters, vectors, and matrices, is not tested on the AP exam (official course framework).
Our broader rolling syllabus also includes enrichment and a bridge to Calculus. Topics such as formal differentiation, convergence tests, and probability are not presented as AP Precalculus exam requirements. We prioritize the assessed topics for students sitting the exam.
If f has domain [−2, 8] and g(x) = f(2x + 8), the input 2x + 8 must remain between −2 and 8. Solve −2 ≤ 2x + 8 ≤ 8 to get −5 ≤ x ≤ 0. Domain restrictions follow the input, not the appearance of the outside expression.

Frequently asked
Every SOMATH class is capped at 6 students. That is the number that lets one teacher see every student's work in real time, correct silent mistakes before they become habits, and pace to the room instead of the average. Larger groups defeat the whole point of small-group teaching, so we hold the cap firmly.
In person at 226 W 79th Street, 1st Floor, New York, NY 10024 — one block from the 79th Street 1 train and a short walk from the B and C at 81st Street. We do not offer online classes; the small-group model relies on shared whiteboard work and in-room feedback.
The $99 one-time registration fee is separate from monthly tuition. Workbooks and practice materials are included as described in the enrollment terms. The free 30-minute evaluation is available before enrollment and does not require payment.
Yes. Cancel anytime with 15 days written notice — no long-term contract. One free make-up per month for a missed class (subject to available seats in another cohort).
Yes. Every new family starts with a free 30-minute evaluation in our classroom plus a written diagnostic delivered within 48 hours. There is no charge and no commitment — the diagnostic is yours to keep whether you enroll or not. Book at schoolofmath.us/evaluation or call (646) 668-6151.
Both. AP preparation focuses on College Board Units 1–3: polynomial and rational functions, exponential and logarithmic functions, and trigonometric and polar functions. Unit 4 is not assessed on the AP exam. Our broader rolling syllabus also supports traditional Precalculus and enrichment, with the study plan adjusted to the student’s school course and target.
