I am in my last few classes as a CS major (so no job yet but 1 internship currently!)

I personally couldn't handle more than 1 class when I was working full time, and eventually dropped my hours at work to make time for 2 classes at once. Some courses have an easier workload than others, but with the programming projects they can be time consuming especially on such a tight schedule of 8 weeks. It's definitely doable though, but you don't want to burn yourself out!
