So if I were to fail the AP test but validate on ABS, would I validate the class or would the AP test cancel it?The ABS has questionnaires and math exams. Chem/physics/English/foreign lang on the ABS are just questionnaires and the real validation exams are taken during Plebe Summer. The only way to validate Math with an validation exam is on the ABS. No math exams during plebe summer. Also, AP scores trump validation test scores.
