Dear Venu, as per my opinion the choice is between only two MCA and MBA. MCA is always a better option than MSc.

If you are interested and good at programming and mathematics and want to see yourself as a Software Developer in the future, then go ahead with MCA.

If you are just interested, but not good at programming, and still want to see yourself as a Software Developer in future, then opt MCA but you'll have to work harder, join additional courses and learn to code properly.

If you're not planning on becoming a Software Developer, but just fascinated with the IT Industry, then opt for MBA in Information Technology.

If you have lost interest in the IT world after completing BCA, then opt for MBA.

Now, the harsh truth. There is absolutely no point in pursuing a course in MBA from any random college or university. If you want to make it big, then join anyone of the most reputed Business Schools (preferably in the Top 10 list) by cracking their Entrance Exams and excel in the subjects there to make your way into interviews for jobs that pay you more than you what you'd need. You'll have to study and work hard for two years. Getting a MBA degree from any random college with average marks will land you a job of a telemarketer or salesman or somebody's assistant or something like that unless you get some recommendations from someone in the big league.

All the best

Hope this helps
