How Much Time Do You Spend Preparing for SAT IIs

<p>I'm preparing for SAT II Bio, which I'm taking in October, and I've started reading the Kaplan book. How early did you guys start? And how much time each week did you spend studying? Thanks!</p>

<p>I took honors biology freshman year, AP biology sophomore year. I took the SAT II in may near the AP test date. I used Campbell's biology and Cliffs AP to study for both. I studied/crammed for the 2 weeks before the SAT II, and received a 710</p>
