Yes, colleges take the highest SAT score of all the SAT scores you submit. For example, according to Charlotte M. Klaar, Ph.D., Director, Klaar College Consulting, “If You take the SAT in March and get a Critical Reading (CR) score of 550, Math (M) score of 650, and Writing (WR) score of 540. You then take it in May and get CR600, M620, and WR550. You take it again in October and get CR620, M590, and WR510. The Superscore would be CR620, M650, WR550; it is this set of scores colleges should use for placement.
