<p>It’s very difficult to get above a 3.7. The mean GPA for the natural sciences is the lowest: a 3.12 (compared to a 3.35 in humanities). Only 35% of the class gets A’s in all science courses: they are curved very strictly.</p>
<p>Princeton’s a great place though - they’ll challenge you and force you to learn. If you want a more laid back environment though, Princeton is definitely not the place. Getting a 3.7 science GPA is like getting an A- in every science course: you were in the top 35% in ALL your classes, where on your left could be physics/chemistry/biology international Olympiads, and the kids to your right finished multivariable calculus in 10th grade.</p>
<p>Oh, and correction: the median GPA is around a 3.4. I think the mean is around 3.3 (there a few kids who have significantly lower GPAs, bringing the mean down).</p>
