I'm trying to practice doing the SAT math 2 this summer, and I realize that I just couldn't keep up with the pace of the test. I took the test once and I got a 670 with 10 questions that I didn't have a chance to finish. I also want to take the chemistry portion of the SAT, but I have never taken a high school chemistry class, just one semester of college chemistry. What topics are on the SAT chemistry test but not in 1st semester college chemistry? I generally have a hard time keeping pace on math tests and am often the last one to finish (since I'm use to taking tests with no time limits). Any suggestions to improve my scores is highly appreciated. P.S. Since calculators are allowed in the test, how important is the use of calculators on the test, especially calculator programs?
