<p>Um. it really depends. I spent some time (like once or twice a week) from Februrary through April studying, then really kicked it up in May. I wish, in retrospect, that I had studied more.</p>
<p>I do think that, if you review well (don't just take the exams, but figure out how they are structured and learn the shortcuts) that you could review your way to a much-improved score. </p>
<p>Take a practice test, see how you do, and consider what score you are aiming for. I got a 163 or something on my first practice test, so I figured that I didn't need to kill myself studying.</p>
