<p>I'm planning to take SAT II for chemistry (or bio), maths II and chinese this December. It's my first testing and I'm completely/utterly clueless about the following:
1. What books should I use? What do you recommend?
2. Is it better to take all three at once, or take them one by one? maybe two by one or one by two?</p>
<ol>
<li>Barron's if you're aiming for 800. PR for 750+.</li>
<li>If you have a good SAT 1 score, take as few subject tests as possible each month. If your SAT 1 score is bad, focus on that and take all 3 subject tests at the same month.</li>
</ol>
<p>for math SAT II, just study your algebra II and precalculus books. pay attention to fundamentals in math class. brush up on algebra II and precalc concepts that you don't quite get.</p>
<p>I recommend taking the tests one by one. that's what I did and it got me 2 800s and a 790. it was much less stressful for me. i took my foreign language SAT II in the fall of junior year. I was ready for it, and it wasn't stressful. i took another SAT II in january of junior year (again, didn't have to prepare for this one, so it was relaxing). i took the SAT I in april, then took APs in may. I took one SAT II in may, the day after the corresponding AP exam. i liked how i did my testing--never more than one SAT test per day. try to spread out testing if you can. it's relaxing and gives you time to retake if necessary. and you dont have to prep for 3 tests at once.</p>
