I've reached a point of no return in my learning computer science journey. I know little bit of basics, but advanced stuffs in computer science I really don't know. By advanced stuffs, I mean subjects taught in 3rd and 4th year of typical CS degree(which are also called core CS subjects in some parts of the world, subjects like Operating System, Database,Computer Network, Artifical Intelligence etc).<p>I'm really bothered by it. I want to learn Computer Science. I'm already graduated though. But I graduated from almost a degree farm(I didn't know when I joined), so my graduation doesn't mean much.<p>About me, I find Electronics part of computer science easier though. I finally want to study OS, DBMS, CN, DSA, AI etc like taught in college level course and I want to do it right. Feel confident in my learning. How do I do it?
Just starting to study the things that catch your interest. Keep studying them so long as they hold your interest. Then stop. Maybe come back later. Maybe not.<p>There's not a test on Tuesday the fourteenth and the self-study of databases isn't a class that ends after twelve weeks.<p>Learning after finishing school doesn't look or feel like school. That makes it hard. Particularly it is hard to start because it requires giving yourself permission. And it is hard to keep going because learning is the process of being less bad at something that you are bad at and that means doing things you are bad at.<p>Anyway, just start and struggle. good luck.
Most of these subjects are not especially well-taught in college CS courses. You're in a golden age for being able to learn whatever you like: you can start by plugging keywords into YouTube and looking for popular video explanations of how to solve problems in that field, including screen sharing of live tutorials.<p>I especially don't think anyone gets expert-level knowledge of databases <i>and</i> machine learning <i>and</i> operating systems from their CS degree.<p>Consider the possibility that you're actually averagely prepared for a graduate, and this is the part where you mainly need to decide which disciplines actually interest you.<p>G'luck!
