I study at uni which is mixed, I only have a 2years left. But in my case I can do most things at home without interacting with non maharim. I can also choose courses I think will have no group projects. There is however doubts regarding wether or not some obligatory courses will bring fitnah.

If you are able to avoid that which is forbidden then there is nothing on you.
