<p>I've taken regular Chemistry and Biology. Is it enough to take SATII Chemistry and Biology? Or it needs AP Chemistry and AP Biology as well?</p>
<p>And can anybody recommend some books that contain both the content and the practice test? Since I'm afraid I've forgot all the things..
Chemistry: I am going to buy Barron and Kaplan.
But I'm not gonna buy PR because it is said to be too easy compared to the real test. Is that true?
Biology: Sparknotes and PR.
I have no other idea of other books. </p>
<p>Thank you.</p>
<p>AP chem is not required. Ask your teacher how other students have done, and whether your chem course covered enough of the subject test. Also, pick up CB's Subject Test book and take a practice test, and you'll know within an hour how strong you are.</p>
<p>I only took regular chem and I was two months into my AP Chem class when I took my SATII Chem. I studied about 12 hrs/day over a week with the Barron's book, memorizing everything except for Organic Chem. For that, I used PR. I also reviewed concepts I had difficulty understanding with PR because its explanations are so much easier. I also memorized both book's lab stuff. The proof is in the pudding. I got an 800 on the test and I know for certain that I only omitted one (a really specific one asking what gas is used to make glass) and got one wrong due to carelessness. I would definitely recommend using these two books. I had Kaplan but I didn't look at it at all and luckily I didn't need to. Best of luck to you!</p>
<p>BTW, before studying, I took the Barron's diagnostic test and I think I got around a 630.</p>
