<p>It’s more about the quality of your practice than the quantity. There is no sense in repeating the things you are doing wrong over and over. That will only reinforce your mistakes. I am a tutor and i see it all the time. Students come in having done every practice test in every book out there and then ask me why they are not improving. My job is to spot the patterns in their errors and fix them. I put a stop to taking practice tests until that problem is fixed. Self study can only get you so far. There are many great SAT tutors all over the US, but make sure you get word-of-mouth references from your friends. School teachers are usually not the best SAT coaches - don’t insist on that credential when making your choice.</p>
