UCSD checklist for admitted student

Hi guys, after getting accepted from UCSD, I have been taken to the checklist page where I needed to complete them before the deadlines. However, the list is so long and many things to do, such as alcohol survey, TB disease health check, etc. I have done some already, yet I am wondering whether the school would turn me down if I missed the summitted deadline.
Thank you!

In general, the checklist needs to be completed prior to registering for classes but I would not push the deadlines too far. A deadline is there for a reason.
