After bachleor degree in computer science what should I prefer? Masters? Or PGD? Please it would really help, thank you.

Hi, Milan,

You're the only person who can answer this question, and the best approach is to "begin with the end in mind".  Ask yourself, "What do I want to do once I finish my studies? Teach? Work for a tech firm?  Become a computer science researcher?"

Armed with the answer, you can then figure out what are the requirements to get the job you want. For example, the top consulting firms tend to only hire MBAs from a top school. And for many jobs in Computer Science research you're required to have a PhD. If your goal were to get one of these jobs, you'd know which degree to pursue.

If you don't know what kind of job you're after, then my recommendation is to try to find a position that you think you'll find interesting and uses what you learned in your undergrad studies. You can always go back and pursue an advanced degree when it becomes important for what you're trying to achieve. 

My husband only started his PhD in Computer Science a decade after finishing engineering school, because he wanted to shift from working as an engineer to doing research. Once you know what the degree is for, then it makes sense to go for it.

Good luck!
