Did any of you take hardcore AP science classes in highschool?  as in year of chem/physics/bio/calc and aced AP exams with 4-5?  That way it was easier during your college career to make As because it was the second time for you to take the class?  Kind of like a GPA booster.  I just want an honest opinion, if I would have done things differently this would have probably been the route I would have taken.  Although my highschool only offered AP Bio.
