<p>Hello. I just finished my sophomore year of high school and Im going into my junior year. I am taking 3 AP classes, with 2 being Chem And calc. I really want to take advantage of the summer by preparing for those 2 subjects. I want to master the prequisites and perhaps even get a little head start. I really want to purchase some AP prep books but I don't know which ones are the best. Barrons? Kapplons? Princeton review? Please do help as I would to purchase the books as soon as possible. Thank you</p>
<p>You don’t need prep books for calc, Trust me just do the released exams. The problems tend to be VERY similar every year.</p>
<p>same question</p>
<p>Agree with the above poster, a prep book for calc isn’t really necessary (unless you have a bad teacher).</p>
<p>Chem- Bozeman science and Khan academy videos. Khan is especially good for titrations/pH and electrochem. The prep books for the new exam are all very disappointing. Also, the official practice exam is incredibly beneficial. PM me if you want a copy.</p>
