Okay, with about 7 weeks left until the October SAT...I need a strict study plan to bump my score from a 1750 to 2000+. My Verbal (500) Math (620) Writing (630)...My goals Verbal (650-660) Math (670-700) Writing (650ish). On the March exam, I screwed up Verbal because I used multiple strategies and didn't stick with one where I confused myself. I have only 2 tests left in the Blue Book and the free online exam from TCB, so I'm seeking more practice exams. My strategy was to sit down one day and take the full test and based on that target my weeknesses by reviewing them in the Princeton Review workbooks. Then I'd follow it up with another diagnostic and see how much I improved. The problem is...its kind of difficult to take out 4 hours of a day to take a test. Is there an alternative? I'd really appreciate it if someone can help me out with a schedule/plan. Thanks!
