It depends on what you plan to be. To be honest with you, studying isn't worth it. I dropped out of college when I was in my 3rd year and I don't regret it. But I'm very lucky, in that I got a job soon after. If you would like to do something of your own, please please get started as soon as possible. Don't wait for anything. Just start it now. A company, a skill, anything! Start it now and by the time you graduate or by the time you would have graduated you'll be really good at it or have a proper company, etc. So, read on. Learn. But make sure it leads somewhere good. You're an Ethiopian, there's not much room to make mistakes. But taking the risk of learning more, of discovering more can actually be better. Good luck.
