<p>Like the others have said, work carefully! Here's some of my tips:
1. As you work through the problems, circle the correct answer in your test booklet. Bubble your answers in in blocks. If you get stuck on one, mark it and skip it (make sure not to make a mistake on your answer sheet though!)
2. When you finish, go back and make sure the answers in your test booklet match the answers on your answer sheet. Also do the questions you skipped.
3. After step 2, go through and check each question, starting with the first. Reread each question carefully.
4. Go through your previous tests, and work through every single problem you missed or had trouble with. SAT math problems are very predictable and the same ones tend to show up over and over again.</p>
