Which course should I pursue to get into IT field?

You have entered in IT field already...as u hv completed ur BCA. Now either you are looking for a job or higher studies. I would suggest pursue MCA and choose one particular field to excel n master in it.

If you have completed your BCA program, then you are eligible to join IT industry now itself. You can also plan to go for PG program which in turn will help you get better job prospects in future. You can prepare for MCA which is the most popular course after BCA.
