Sat chem/ bio sunject test

<p>I took regular bio and chem 2 years ago and I am studying my guts out for sat ii chem.
The problem is Bio do you think I can possibly take bio for a good score in November I am a senior and taking ap bio this year. We are only on chapter7.
Do you think I should take bio subject test in november.
Any Advice for sat II chem and bio?</p>

<p>If you do take sat chem, I highly recommend the Barrons book!
Some people say it has a lot of unnecessary material, but I thought the over-preparation really helped me.</p>
