Take the PreSAT practice tests as often as you can starting your sophomore year in high school (without getting burned out). Start taking the true SAT at the latest your junior year. Take the actual SAT test no more than three times though. You will need these test scores to be as high as possible for college entrance so study, practice and test often.
