<p>I took biology M last month (May), and totally screwed up. I have missed like over 10 questions already. For preparation, I read the Kaplan, and PR, and even took lots of practice tests. I got 800 when I took the Collegeboard practice test, but then on the real thing I found the test so much harder. So the question is was it because the test this month happened to be harder than usual, or do I need to study a lot more? Do you think the test in June is going to be easier than this one, or will it be about the same level? Thanks</p>
