I have completed bca from an open university in 2012.So,which course now I can do to get a good job in IT?

You can go with network certifications.ie ccna,comptia network+ etc

Ain, I am not sure how good you are with maths and programming. If you are, then you must pick up a language whether PHP/ HTML5 (web dev), .Net (for software dev) Java/ Android (for apps) or C#/ Unity (for games). However like i mentioned, you must be good with programming to move ahead in this area

Ain, do understand where you stand since most of the good companies hire only BTech or MCA. However, if you're creative, you can always consider going for Design and Animation. A good mentor and wise selection of courses with a good school, followed by diligent learning, would get you a head start i

You can complete PGDCA or MCA after BCA. You will have good opportunities ahead. Good Luck.
