<p>Hello everyone,
I'm an incoming sophomore and i took honors bio as a freshman.
I have been studying for this test since the beginning of the summer.
I used Kaplan, Princeton Review, and McGraw- Hill's sat 2 bio practice books.
Do these practice books cover the essential materials for the test or no?( Enough detail?)</p>
<p>Thank you for all of your answers, and also if you have taken the test can you please give me some advice on the difficulty of it...</p>
<p>P.S. Is it true that the difficulty of the sat 2 test ranges depending on the test dates?( I know this is somewhat stupid and all but I have heard of this and I am just curious)?
