Help on SAT Subject Tests Preperation? (Bio E & Math 2)

<p>I'm a junior right now, and hoping to apply ED this coming fall for a certain school.
Anyhow, they require I take any two SAT Subject Tests, and I've settled on Math 2 and Bio E. The only problem I have is that I haven't prepared for them, at all, due to short notice.
I've only taken an Honors Biology course and that was freshman year, so I'm kind of worried for the Bio test. Also, I have to take the test in June, and that's the only chance I have to take it because like I said, I'm applying ED to that school.
I won't consider taking any other subjects because those are the ones I'd feel most comfortable with (although I may consider Literature, but I here it's pretty brutal? But, I usually do test better with Reading than Math, at least school wise and on state standardized tests). But yeah, what do you guys recommend; certain books, online tests, etc.?</p>
