The best time to take the SAT is when you are in 10th or 11th grade (SMA 1 or SMA 2) after you have learned Algebra and Geometry. Since you may need to retake the SAT, it is recommended that you take the SAT as early as possible so that you will have time to improve your score. Don’t wait till your senior year; you will be busy with college application and any subject tests (SAT II) or AP tests.
