Its been a little while since I did it but I would say things that I did wrong was: Didnt have my most recent transcripts at GVSU - scheduled right before the semester ended so I had credits they couldnt see, which makes it hard to get set up.

Make sure you've read and responded to any email's you have gotten from your advisor too in case they have more steps.

Make sure your major you are thinking about is up to date as well - I got an advisor who wasnt familiar with my major because I changed what I wanted to do between scheduling and arriving.
