Loose Screws (1985)

What happens when four high school screw-ups are forced to attend an academy summer school to graduate? They turn their scholastic sentence into a wacky game of trying to improve their scores... with the women. The ultimate conquest for the 100-point prize is the sexy new French teacher, but she proves to be a bigger challenge than their failing grades. The unforgiving principal foils every scheme, and their sidesplitting last chance is the academy's anniversary celebration.
