<p>Princeton grading may be tough. However, it is a no-brainer to choose Princeton over any state school, unless you have full finnacial aid. To my knowledge, the average GPA for Princeton students accepted into Medical Schools is 3.4. For you to be competitive from a state school, you had better have at least 3.75. If you screw your GPA in Princeton, you still a Princeton graduate, and have better chance to advance yourself in other graduate schools or employment. If you screw your GPA in a state school, you will be in deep trouble in pursuing anything, unless you create your own employment or have a family connection for jobs.</p>
