<p>It’s really just a matter of personal preference - do you want a couple of days in between the SAT Subject Test and another one of your tests - or do you want them close together?</p>
<p>Best book i used was barrons, but i think i solved nearly all the practice tests available not just barrons.Solve as much as you can.The day before test i looked at all practice tests again ,especially reviewed my wrong questions.Last day review earned me like 2 or 3 questions in real test.
Hope you will get what you want.</p>
<p>ONE BOOK IS NEVER ENOUGH.ALWAYS TAKE A LOOK AT OTHERS.
AND I NEED TO USE CAPITAL LETTERS :D</p>
<p>Got an 800 on Chem a while ago… best thing I remember helping was the usnco (chem olympiad). I’d say if you make it to the second round you pretty much have a guaranteed 800.</p>
