CS35L Waitlist Policy

Hi, I just got in the waitlist for Eggert's 35L in spring. I was wondering what is the policy for 35L. Do they enroll students over capacity like how math classes usually do, or do usually enough people drop the class such that people on the waitlist can get in? What is Eggert's PTE policy? I've check his websites and he has provided advice for people not enrolled and not on the waitlist, but not in regards to waitlisted students specifically.

Any info would be greatly appreciated. I really hope that I could get in by the end of Week 2 instead of being dropped from the class.
