More important than the GPA, prestige or credits is the ability to get ahead of the curve because of prerequisites. In math many classes are closed to you without a year of multivariable and pretty much everything interesting is closed until you've taken first year calc. The same is going to be true to varying degrees for biology, chemistry, physics, computer science, psychology, econ, etc.
