How does studying abroad works

I will be going to attend cuny- city college of New York and I’m interested in study abroad. I was just wondering,
If I study abroad will I be missing on any other of my classes?

Can study abroad be accounted from my tuition (considering I have extra)

Best thing to do is to start by reading all the info on your college website.

Some financial aid can apply to your study abroad you just have to check and see. All my daughter’s aid covered her abroad program and her living expenses overseas. She also applied for a Gilman grant which covered transportation and more.

Also see the advising hours that site talks about? Go to them and ask your questions.
