Why can't i do well on the sat?

<p>Every time I take a practice one at my SAT prep class, I manage to do every question (with reasonable guessing due to elimination) and I think I do very well. But I keep getting between 1700 and 1800 EVERY TIME. Math I usualy get around 650, but I think I ace it. Reading 600, though I think I get over a 700. And writing being my weakest around a 550, but I never feel I did that bad?</p>

<p>Any suggestions I should try next time I go at it? It's frustrating knowing I can get a MUCH higher score, but not getting it....</p>

<p>analyze your mistakes and see what patterns there are. then try and self-correct</p>

<p>What types of things are you missing and for what reasons?</p>
