In my frequent conversations with students, parents and educators I am often asked if a person mix and match scores from different SATs?

The answer is Yes.  If a student scores a 550 on the verbal and a 600 on the math on the May SAT and then scores a 600 on the verbal and a 550 on the math on the October SAT, then the student can use the 600 from both exams to report to colleges that he or she has a 1200.  This is the accepted practice when applying to schools.
