"Bad" and "good" are meaningless judgements in this context. You're about to graduate, so you wouldn't be expected to have any real experience, but you do have experience building and running an actual product. Seems to me like you've got the time ahead of you to try running your startup and either succeed or fail, in which case you'd have enough time to restart your career as an employee.
My only advice would be: the founder mindset is very different to the employee mindset, and you'd have to take that into account, and, don't quit your CS degree if you're within 1 year of graduating.
