First Year Student (HELP!)

I just got accepted off of the waitlist (yay!) but everything is so confusing... and I want to make sure I have everything in order (especially with financial aid)

Will I get a date to meet with an advisor? How do I sign up/ find dates for orientation? Will my advisor help me figure out financial aid or is there a different department I should contact?

I've been looking on the SBUportal site, but I feel like im running in circles there...

(Links/ any info will be extremely helpful!!)
