Need book for Chem or not?

<p>I got 100% on that. Does this indicate anything about my performance on the actual test?</p>

<p>The TTCE questions were the first time I had ever seen them and they do seem to be the hardest part of the SAT II, but they seem pretty easy.</p>

<p>Also, the fact that a calculator is not permitted makes me a lot more confident so you won't have to use any equations (less memorization) except for stoichiometry/dimensional analysis.</p>
