Mosaic is stopping me from enrolling in certain classes that have overlapping tutorials. Any ideas on how this can be bypassed if I don’t mind the small conflict?

Me as well, also ECE. Waiting on a reply from Jeanne.

You need approval from your associate deans office to take courses with conflicts. The system will prohibit you unless you explicitly get permission to take courses with conflicts. There are specific criteria you need to meet in order for you to proceed with a conflict (ex. required for your program, need it for a minor, etc.). You cannot keep a conflict just so your class timings are better (or some reason like that), they've gotten stricter on this.

Ok thanks. For others interested, this is the form we fill out to request it:
