What are the 1st Year Online Grad Student Must Does?

I’ll be staring TTU online this fall and I want to make sure I’m completely on top of everything.

What are some things I should do that aren’t brought up by advisors, professors, or on the Grad student checklist?

1. Admissions/Registration wise I MUST do before the start of the Fall semester?
2. Anything student life wise? Probably not much since I’m an online student but maybe there’s something that I haven’t heard of yet.
3. Anything I need to do with financial aid/tuition? That’s not the basic stuff that I could just look up.
4. Anything regarding accommodations (not, you know, applying for them)?
5. Any area I missed that I would benefit from completing before the semester starts?
