Practice, BB, and PR dont work?

<p>hi…i am currently taking the CB online course(with the BB too)…a princeton review course and i have at least 10 other books for the new sat and each of its sections…</p>

<p>The only problems is, for the past 2 months i have veen learning everything and practicing ALOT under timed and not times conditions…i go over all the right and wrong answers to each but i am STILL not seeing an improvement…my grades satay the same (450 each) and they fluctuate 10 points sometimes…</p>

<p>WHY ISNT ANYTHING WORKING!!!</p>
