A structured summer prep course for students taking Honors Precalculus in 9th grade — or anyone who wants to walk into precalc feeling ready, not anxious. 36 video sessions. 11 chapters. Free start.
Most online math courses give you a screencast and call it a day. This one ships everything you'd get in a real classroom.
36 sessions, ~10 min each. Concept explanations paired with custom Manim animations that show the math in motion.
Follow-along PDFs structured exactly like the video. Print them, write on them, refer back to them.
Practice problems for every session with full answer keys. Self-check and learn from mistakes.
Short 5–10 minute quizzes after each session to confirm you've got the concept down before moving on.
A printable formula card per chapter — everything you need on one page, ready for the night before a test.
Full-length chapter tests with answer keys plus extra practice problems for deeper review.
Bonus 3-session calculator walkthrough. From “I just unboxed it” to “I can use this on a test.”
Plain-English definitions for every technical term, organized by chapter for quick lookup.
A reference of the most common errors students make per chapter — so you don't make them.
Built to mirror a full year of Honors Precalculus. Skip what you know, dig into what's hard.
The foundation: coordinates, slope, and what makes something a function.
From parabolas to higher-degree behavior — and complex numbers when zeros go imaginary.
Growth, decay, and the inverse relationship that powers them.
Angles, the unit circle, and graphs of sine, cosine, and friends.
Identities, equations, and the formulas that unlock harder problems.
Beyond right triangles — and a first look at vectors and polar form.
Solve big systems — and meet the algebra of matrices.
Patterns in numbers, sums, induction, and combinatorics.
Curves that don't fit y = f(x) — and the coordinate systems built for them.
Step into 3D — coordinates, vectors, lines and planes.
Where precalc ends and calculus begins.
Bonus reference — pick up calculator skills as you need them across the course.
6 sessions free — TI-84 Primer plus all of Chapter 1. No credit card.
Less than one tutoring session. Full-year access. No subscriptions.
Ask questions, share workings, see what others are stuck on. I read it regularly and chime in when I can — no response timeline.
Beyond the free Chapter-1 sessions, the channel has short clips with concept reminders, alternate explanations, and ideas that don't fit the main course.
Rising 9th graders heading into Honors Precalculus, current Honors Precalc students who want a stronger foundation, or homeschoolers needing a structured precalc curriculum. The pace assumes Algebra 1 and basic geometry.
Both are mostly video — and Khan especially is a great free supplement. What they don't ship is the rest of a course: worksheets with full answer keys, end-of-chapter tests, quick-check quizzes, a printable formula card per chapter, a chapter-organized glossary, and a common-mistakes reference. If you've watched a free math video and then thought “OK but where do I practice this?” — that's the gap this fills. The videos here also use custom Manim animations instead of whiteboard screencasts.
12 months from the day you purchase. That covers the full school year plus summer review on either side.
Around 30–40 hours total if you watch all videos and work through the worksheets. At 1 session per day, that's about 5–6 weeks. Self-paced — go faster or slower.
Recommended but not required. The TI-84 Primer (3 free sessions) gets you up to speed if you have one.
No — this is a self-paced video course. The tradeoff: it costs $29 instead of $1,000+ for tutoring. Worksheets have full answer keys so you can self-check.
Yes — full refund within 3 days of purchase, no questions asked. Chapter 1 is on YouTube as a free preview, so you can verify the teaching style before paying.
