<p>Mine has a pile of advanced courses under his belt and talked to folks a bit about placement. I have the strong impression that it is well done and tends to be highly individualized. They have a lot of kids with strong backgrounds who have done widely varying things - self study, tutors, and courses at community colleges and universities, and online courses too. So, the school is flexible - there are various exams - some online and some sent over the summer and some done during orientation. And there is talking to the department.
So…don’t worry about placement. From what I have seen and heard, they will do a fine job.</p>
