Using AP 5's to avoid entry level classes

I have received a 5 on the AP Bio, Chem, BC Calc, and Physics C: Mechanics exams. Would it be better for me to use my scores to advance into the upper engineering divisions during my first year instead of the entry level classes/weeders? Or should I go through the entry level classes and use them as GPA boosters? I'm worried about advancing too fast and ruining my GPA.
