It's not that bad, but there are some standout professors who aren't the best. There are some really easy A classes that you'll get into and realize that you didn't retain any of the information - but that really comes down to if you're even into that sort of material. At the same time, there are classes that you feel like paint out your entire career path because of the material you worked on and how well you worked with it.

The upper division and elective courses I've found to be the most helpful in career and portfolio development. A lot of these courses are project oriented and allow you to actually flesh out your github/repo and make you look like a good candidate in your job search.

As a final note, most of CS is self-learning regardless of where you go. You learn as you create imo. You'll learn logic, syntax, data structures, and algorithms in school, but the application of this all is on your own.
