Nondorf apparently just announced that the mean SAT “was well over 1500” or something like that. if you use the College Board’s practice tests, just know that they have re-scaled the Math section for the real test. Your current Math score is based on current scaling but the practice tests - some of which came out PRIOR to the first administration of the new test - might have very different scaling. Look to actual #'s of problems missed, level of difficulty, and so forth, rather than scaled score, to gauge your degree of improvement.
