<p>I’m taking the SAT II Chem and Math IIC. The first practice tests i took, i got 580 on chem and 680 on math. on the second practice i got 700 on chem and 580 on math. i didn’t really study for either. how’d i get a lot better on one but a lot worse on the other?</p>
<p>Well, you said you really didn’t study for them, so maybe your mind was subconciously neglecting one over the other. If you don’t study, chance tends to play a larger role. Advice: study.</p>
