Which colleges with low fees and high average packages should i target? And which IITs should i register for?

Hi ernee,
While you will certainly get callsfrom new IIMs, you are on the border-line when it comes to CAP ccall.
IITB usually requires a score of 98+, it is out.
IITD gives call at 96+ but they have prominence to work-ex, hence it is unlikely
Yet, you can apply to IIT-D, IIT-kgp, IIT-madras and IIT-kanpur
MDI is the best possible convert at this percentile
You can have fallback options of IMI & IMT
Wish you best of luck:)

Check the IITs which take non-engineers. Many don't.

As far as non-IITs are concerned, for a non-science background at that range, MDI, New IIMs, IIM K finance are good. DU's Finance course is also cheap.
