No problem. In response to the other question you asked, I am not sure if Professors can give permission for non-registered students to attend their class. I think it has to do with tuition, etc. He can certainly contact Professors and show interest. They tend not to have too much influence on getting in from what I know. Athletics, even at Vassar, remains the one area where coaches can get kids in. Kind of ridiculous but that is how it is. Another thought is that he might be able to tag along with another student. My son attended class with his cousin but it was during an open house (not at Vassar) and things were pretty relaxed. Good luck!
