To get into state schools, the score to get in is not all that high. Also, you can always retake it. The colleges only really look at the overall score so your writing and language can help balance out your math score. There are different ways you can prepare for the SAT ranging from getting books on it to taking an online course.
As most colleges say, scores aren't everything. You can still get into a good college after bombing the SATs. However, it does present the admissions committee with a reason not to accept you. Think about it this way: if you offer something else to the school that none or very few people can offer, you will be fine. But if it comes down to choosing between you and a person with a profile very similar to yours but with better scores, the college will obviously take preference over that person. This does not exclude the chance that you are both admitted, however.
Overall, scores are important - but only if you don't have anything else to show off. Try to find a good "hook" and as long the "hook" is a good one, you will not be at a disadvantage.
SAT (or ACT) scores are generally only one of a myriad of items a college/university will examine in regards to your admissions. Read my article on the SAT and Admissions (at http://collegeuniversity.suite101.com/ar… in the College/University section of suite101.com. Then contact the admissions office of the college/university you are interested in attending for specific information on this issue.
