<p>How good are the Barron's books for the two subjects?
I'm taking both on June 5th, so in a week and a half, I've already taken the diagnostic tests in the books for both and started reviewing for math but I just started reviewing for bio today.</p>
<p>I seemed to a lot worse on the bio diagnostic test even though I took the AP exam for it in May..
Are they super hard compared to the actual test? Is there anything you'd recommend for this last week and a half (for both tests)?</p>
