<p>Less important than the grading scale itself is going to be grade deflation. Princeton is notorious for it, while other private institutions are going through periods of rampant grade inflation. </p>
<p>Remember too that in college, grading isn’t aligned to a particular scale but rather to a curve. How demanding this curve is will depend on the sorts of classes you take (ie orgo, a weeding-out class for pre-med, is not going to be easy) as well as how well you perform against the kids in your class. For one class, your percent out of a hundred may be your actual grade, because the test is so easy almost no one misses a question. For other tests, getting a quarter of the questions right may get you the highest grade in the class.</p>
<p>In short, this isn’t a question that can be answered. Grading will be dependent on the class, as well as the particularly college’s standards (ie Princeton, where only a certain percentage of people in a class can get A’s).</p>
