Some schools allow students to take AB Calculus one year and BC Calculus the next year. Such schools are rare and so this review is in low demand. There's no point in my putting a price tag on it. It is designed to review the most important topics from Precalc that are actually used in calculus and then immediately follow them with an application learned in AB Calc. All questions are intended to be very simple; this a warm-up for their brains to begin the school year ready to learn.
