IGNOU has a Regional Center at Ahmedabad, and you may pursue MCA from IGNOU Delhi in Distance Mode, with your Evaluations and Tests at the Ahmedabad Center. The Distance Program Content of IGNOU is of one of the best Standards parallel to Public Universities and Higher Technical Institutions, with Recruiters around India recognizing the University qualification.

Other Universities offering MCA in Distance Mode include, Suresh Gyan Vihar University, with centers at Rajkot, Vadodara and Surat.

However, MCA is a Technical Course with Labs, Projects & Tutorials and isnt just a Theory Course. For maximum benefits, I would advise you to pursue the MCA Offline perhaps from some of the best Private or Public Universities or NITs and a strong career in the IT/Software/Services Industry.
