<p>I am thinking of taking both AP and SATII for Chemistry and Physics.
I am currently in AP Chemistry and AP Physics C Mechanics class in school.</p>
<p>I already have the McGraw AP Chem prep book the teacher required our class to buy and I am getting a Princeton Review SATII Physics book from my friend. </p>
<p>***Do I still need to buy a SAT II Chem book and AP Physics C Mech book???</p>
<p>I can speak to the chemistry situation, but not physics. The AP test is focused a lot more on quantitative problem solving, while the SAT 2 has more qualitative questions that test your knowledge of specific relationships. However, I would say that the biggest difference is that the SAT 2 uses a completely different questioning style. For example, there is a section where you have to say whether a pair of statements is true and if the first one supports the second.</p>
<p>To sum up: I would suggest getting the SAT 2 chemistry book to look at what types of questions are on the test. This is not necessary though, if you’re on a tight budget. In that case, try doing a practice test from online or somewhere else.</p>
<p>^ Thanks for the suggestion. 
I think I might just do some practice test online for Chemistry, then.</p>
<p>I’ve found that the AP practice books are generally a lot more in depth and comprehensive (and expensive) compared the SAT II books, so I usually just get an AP book and use that for the SAT.</p>
<p>Library. Most have agreements with other libraries and so can get any prep book out there.You just can’t write in the book, not a big deal.</p>
