What would your roadmap be if you were to drop out of college?

Not all professors are the same. Not all universities are the same. If I was in your shoes, I would try to transfer to a different and hopefully better university. Yes, most of what they teach is archaic, impractical, and more theory than practice. With that said, assuming you live in the US ("college" instead of "university"), getting a bachelor's degree is an important credential to get especially if you can get it in CS. I would only consider changing majors if you believe, you just cannot succeed with CS.

If you attend a public university, most states require the universities to disclose "grade distributions" and sites like ratemyprofessors can give you a hint of which university/professors are good or are just horrific. The grade distributions will tell you the letter grades each professor gave each class. I.e., a university/college has the same admissions standards; if two professors teach the same class but one consistently gives Cs while the other consistently gives Bs -- as the Dean of the college or a student, I would be upset.

Well, I would advise against dropping out of college. It is extremely hard for people to go back later. Part of graduating college is proving that you have the ability to stick with something. Believe me, there will be days at a job where you don't feel inspired and having to do things that are not fun. Are you sure you don't want to just change your major, or switch to a different school?

But...

If you have already made up your mind, then I guess my suggestion is to do a boot camp and/or get a certification of some kind.

The problem is you need at least some kind of credential on your resume to keep it from getting tossed out.

Go to work for a small business. It doesn’t need to be a startup. You will get more real world experience working in a small business and interacting with customers than you ever will reading about it as an MBA.
