Forget credit; some students attend summer school to ace classes in fall

Stella Chavez:

Julie Chang is spending the summer learning calculus at a college prep school. In the fall, she’s going to take calculus again, as a junior at Plano Senior High.
Her strategy is simple: Learn as much as possible about the subject over the summer so there’s a good chance of acing the class when it really counts – during the school year.
And maybe she can reach her goal of being valedictorian for the Class of 2010
