But I would say that you're in an environment where everyone cares greatly about credentials, because that's all anyone has so far. Once you graduate and have worked for a few years, people don't care so much about the credential. It may matter some, but it matters more that you can actually do things.
So you need to get a credential that is good enough to get you a job. But it matters more that you actually know what you're talking about, rather than just being able to repeat what the professor said. You need to understand, not just memorize. You need to be able to write software that actually helps people do things, not just classroom exercises. If you can, then you will surpass many who have better credentials than you. It may take a few years, but you will pass them.
