Sorry, you are new to Computer Science. Undergraduate CS only covers a couple of percent of the topic. Do you know distributed systems, machine learning, robotics, image processing, concurrency, NLP, programming language design, hardware design, computer architecture, software engineering, program verification, security, databases, computer graphics, computer history? Probably not.

Read : Abstraction and Specification in Program Development, then read all four volumes of Knuth's Art of Computer Programming. There are lots of courses on EdX, and MIT Open courseware.

Undergraduate CS is just the start, a tiny beginning.

The university is the best place to find a girl friend/ boy fried. Also a great place to make long term friends.
