<p>I want to be exempt from trigonometry/precalculus next school year (half of the year is dedicated to each subject) so I can instead take both AP Calculus AB and BC by the time I graduate. I have to take the final exam and earn an A to pass out of the class before the school year. I did order two books, "Master Math: Trigonometry, 2nd edition" and "Precalculus Mathematics in a Nutshell." I have not really studied yet, other than some rather dull geometry/algebra review and some information about radians, degrees, and the unit circle.</p>
<p>I am fine with math. I am sure I can learn it quickly enough, but I am unsure of what to focus on. What should I study the most, and what are the major important topics I should know well to earn an A?</p>
<p>Thank you!</p>
