<p>its common knowledge that after some point, a person pretty much stops getting better after they have studied a lot. i studied quite a bit for the june SAT but due to AP tests i probably didnt give it my full attention. i have taken a prep class already and taken all 11 tests in the princeton review book but i plan to study a lot more over the summer. i got a 680 math, 680 critical reading, and 720 writing. can i still keep improving? any suggestions on what books to use? barrons?</p>
