I haven't had much experience with Pearson but try asking people who have taken the SAT II physics for their experience. I took SAT II Chemistry and I studied off my high school notes, went over the book briefly, and managed to do fairly well. Try that out first and if you feel stuck/lost or want a SPARKNOTES version of Physics, I know there are thousands of different prep books/companies. Try to go to your local bookstore/library and check out as many as you can. After all, each book focuses on different things and may teach the material differently, too. So try to find the one that you feel most comfortable with!
