<p>Although taking full length practice tests is not the worst way to study, it is very inefficient. Why would a 700 math student waste so much time on level 1,2, and 3 problems. And if you’re a 400 student I sincerely hope you are not wasting time attempting level 4 and 5 problems. </p>
<p>It is ok to only use the blue book to study, but if you do, use it the right way. Save the first 3 tests and the DVD test to use as full length practice tests since these are the only actual SATs, and use the other tests for day to day study in 10 to 20 minute sessions. But try to focus on your current level of ability in each subject area.</p>
<p>After taking your first practice test, look carefully at where you are in each of the 4 subject areas: Number Theory, Algebra and Functions, Geometry, and Probability and Stats (I include Counting and Data Analysis here too). If you’re struggling with Level 2 Geometry, then only practice Level 2 Geometry. If you got all the Level 1,2, and 3 Number Theory questions right, then focus on Level 4 Number Theory, etc.</p>
<p>If you practice with this kind of efficiency, then 10-20 minutes of math prep a day is plenty.</p>
<p>Also, try to focus less on the quantity of problems you work on, and focus more on quality. You’re score doesn’t go up by attempting lots of problems. It doesn’t even go up when you get problems right. The only way it goes up is if you get a problem wrong, learn how to do it, and then get it right. So keep redoing those problems you get wrong every few days until you can get them right on your own. If you get a problem wrong for any reason at all (even what you would consider a silly mistake), do it again a few days later. </p>
<p>Again, note that I am really commenting on the math sections. You can probably follow similar advice for verbal, but I’d prefer a verbal instructor give advice in this.</p>
