Actually, my roommates and i are taking these three courses this semester (and with another course econ 101, my roommate takes math 217). It’s not a easy schedule but it’s possible. I usually spend 30 hours a week and i am handling them quite well. 281 project and 370 project do have very close ddls, but if you start early, you will be fine. I usually start the project as soon as projects release. Eecs 376, in my opinion, is advanced 203. These courses are too abstract for me, and i also have a tough time on them. And an important thing is that you’d better have a study group on these courses, which will make your semester much easier. This is my personal opinion.
