<p>Alright, so I'm having cold feet about the Math II test this Saturday. I'm in precalculus this year, but my teacher is so bad, I haven't learned a single thing in his class. I keep consistently scoring around 500 on the practice tests (granted, it's Barron's and I barely know how to use a graphing calculator, but still) so I don't think I could I score an 800 on the test in just one week (unless I REALLY REALLY study, but honestly, how realistic is this?)</p>
<p>However, I have a really, really awesome chemistry teacher that I've learned so much from (it's chemistry honors), and I feel that if I study, I could probably do very well on the test. </p>
<p>What I'm asking now is if it's possible to just take another subject test on test day? Or, even if I could, would you advise me to prepare for the chemistry test in a week, or really push it to do well on the math II test?</p>
