<p>I have 2 kids at Vanderbilt. Both took numerous AP classes in high school and got more or less all 5s. The public schools they attended are widely considered “the best” in the nation. They are both A&S at Vandy, and have had an EXTREMELY hard time getting As. They can get A-, B+, and Bs with hard work, but As are rare. I don’t know what the problem is. I am certain they are trying, and just as certain that they are intelligent and educable. My guess is that Vanderbilt has a tough grading system.</p>
