See if you want to do a regular course in MCA in a proper coursework then go for Rajasthan University as it has similar kind of curriculum as IGNOU but you will be more likely to focus on your academics. If you want to pursue it in flexible standards then go for IGNOU.

IGNOU is great but if you aren't sincere or self aware then you will not be able to get the full essence of the course from it. IF you think that you are a sincere student who is wiling to learn go for IGNOU, its the best.
