Buddy, so far i know, programming need ur logic thinking, not ur ekonomi, sejarah or wat, i'm now a programmer, last time i only got 3 credits ^^

almost 5 years, i started from certificate, going to finish up degree this year, time doesn't matter much, as long you can achieve your target, nothing matters, spend a few more years building up the foundation is always better, otherwise you can hardly learn anything

programming.....started by learning how to make a word come out like "Hello World!" when you click a button, then slowly go into deeper thing like how to prevent unauthorized access to some area in the program. we also learn how to build a small system for a company (fictional mostly) to manage their company, like staff management, or wat.

there's a lot thing to learn in programming.

and dun worry, most student can't catch up at the beginning, but if u spend more time in practicing when u free at home, u can easily know wat it's all about, trust me.
to become a good programmer, is keep on practicing

it's my pleasure ^^
remember, don't give up, don't ever try to give up

what can you do? depend on your interest...
