I am thinking of doing an online MBA from a top tier college. Thoughts please.

I am working since 2 years in IT industry and am thinking of not leaving job and doing online MBA from a top Institute. I am not very interested in IT and want to change my field in Marketing or Finance side. Fess is 10 lakh rs. Is it worth it. I see this as the best option since I am not very confident in cracking CAT and doing a offline MBA from this type of premier Institute. Please share your thoughts on this. Any kind of comment or suggestion is much appreciated.
