DSSTPrep’s course materials were created to be comprehensive in scope to each subject. Just as you would learn a broad range of facts, concepts and functions during a semester long class, our courses cover those same topics in our flashcard questions. Our materials are regularly evaluated by college professors and master AP teachers matched to the subjects they have years of experience teaching. As the DSST changes the parameters of their exams, we have our courses reviewed and updated to meet those new standards.
