<p>Adding to my previous post:
My S goes to college a 15 minutes’ walk from home, as do some of his high school mates. Over the last couple of years, he’s waved to them on campus but he has not been in a single class with any of them. Because of the huge range of classes available in any college, it sure does not feel like grade 13! He’s also been involved in ECs that are quite different from what he used to do in high school, so he’s made a whole lot of new friends while keeping in touch with old high school friends.
Since you will be living on campus, I expect you will have a very similar experience. And your story illustrates what somebody told me: the best students at state unis are equal to the best students at Ivies–since some pass up Ivies to attend state unis. You will find others just like yourself. Look forward to meeting them and forget about your immature schoolmates.</p>
