I tried to study, but not just CS, I tried a mixed degree, financial and CS. I failed in the financial part. Still I didn't learn anything new in the first 3 semesters for CS. The most things you will learn from your colleagues in your first job. Especially about TDD and Testing. You have like 1 semester about testing in the most colleges, that is way too less. Btw. I live in Germany so maybe the Bachelor degree in CS here is a joke.
