<p>You have to remember that an A at one school might be on par with a C at another school. For example, a student taking all AP level classes in a district where there are a lot of very bright students and where the teacher has a tough curve, it's conceivable that a student might average a 3.0 due to tough classes in courses that aren't the students specialty. Princeton will care far more what classes you take than how you did in them (provided you're decent--not getting D's or F's).</p>
