SAT II Bio Barrons vs. Sparknotes

<p>Hey everybody!</p>

<p>Hope this finds you well. It finds me stressed. Tomorrow I am taking the SAT II Biology Test (Ecology). I took a practice Barron's test this morning and scored a 700 (without much studying). Then, later on today, I took an online Sparknotes exam and completely failed it!</p>

<p>Which one is more accurate, and do you have any cramming ideas/methods?</p>

<p>Thank you so much! :)</p>
