<p>I took a timed practice test today and scored within the 610-650 range. So I guess that's about a 630. I'm trying to hit at least 700. The thing is, I only usually don't know about 4 questions. With a few lucky guesses I think I could even get some of those. The real question I have is how to cut down on carelessness. I feel I know the material fairly-well by now as I've gone through Barron's, but I'm not really sure what's helpful now to get rid of the careless mistakes that cost me so many points. Are there any suggestions on what I should do ? I'd go through Barron's again just for practice, but is there anything that might be more helpful ?</p>
<p>If you already know the material, I'd advise you just practice, practice, practice. Tear through all of the practice tests and try to raise your score each time. If you don't understand any question on the tests, look them up, figure out how to solve them (and if you need extra help, I'm sure you can post or PM here), and commit that problem to heart. In my opinion, the more you practice, the less likely you are to make careless mistakes..</p>
<p>Yeah, carelessness is definitely a big problem for the math section. One suggestion I've heard (and used with some success) is to read the question three times - first for a general idea, then to get down the information and set up your solution, and finally to make sure you're giving the answer being asked for. </p>
<p>Other than really being careful, practice is your best friend. Good luck!</p>
