Is There Such A Thing As Studying Too Much For The Sat?

<p>I actually havent even started studying for my SATs yet, but i guess that there isnt such thing as studying too much. My friend said that his friend studied alot, and she also took as many practice tests that she could, for she had many many SAT prep books- she ended up getting a perfect score, so it pays off. How exactly does one recommend breaking into the study habit for the SATs? I mean, i have so much other stuff to do that im so unsure how to start!</p>
