<p>I took the SAT II Chemistry exam last year after Honors Chemistry and got a 650, but I barely prepared (only read a few chapters of my Barrons review book and did maybe 2 or 3 practice tests) and didn't put the greatest effort in my chemistry class (didn't always do the homework, didn't study enough for tests or get help when I needed it, let my partners do the lab work).</p>
<p>This year I took physics and have forgotten quite a bit of chemistry, but I want to retake the SAT II in October and get an 800. Any advice?</p>
