yeah i didnt even know Kaplan made a review book for this test until it was too late. There's so much that could be on the science section, general science, earth science, life science, physics, chemistry, and only 30 questions! It makes it really hard to study for that section because there is a lot of information to cover. My advice is to just start reviewing a couple months before a little at a time. (wish i followed some of my own advice!!)
