The problem
Most AP prep is built for the two weeks before May.
Review books, cram courses, and practice exams all aim at the AP exam. But your grade in the class comes from the unit tests you take every few weeks, from September to April.
Nothing plans for those. So you cram the night before each one, and in April you relearn all of it for May.
preptrak plans for both.
The curve x2 + xy + y2 = 7 passes through the point (1, 2). What is the value of d2ydx2 at that point?
- A−45
- B−225Your answer
- C−42125Correct
- D42125
Once: y′ = −(2x + y)/(x + 2y) = −4/5 at (1, 2).
Again: 2 + 2y′ + 2(y′)2 + (x + 2y)y″ = 0, so 5y″ = −42/25.
Why not B: y′ changes with x too, so the derivative of 2y·y′ includes 2(y′)2. Dropping it gives −2/25.
How preptrak works
A plan to every unit test, and to May after that.
Tell preptrak your course and when your next test is. You get a day-by-day plan built from a short diagnostic, and it keeps adjusting as you practice.
Every plan includes:
Your test dates
The plan works back from each unit test your teacher sets, sized to the time you have each day. Test moved? Change the date.
A short diagnostic
A few questions show which topics you already know, so your time goes to the ones you don't.
Questions at AP exam level
Written to match the difficulty and format of the real exam, with an explanation for every answer choice.
Review that carries to May
Earlier units come back in short sets all year, so April isn't spent relearning September.

A plan that moves when you do
Struggle on a drill and tomorrow gives that topic more time. Miss a day and the work shifts instead of piling up.
