Your UG aggregate is low. If your aim is to enter into some Good MFE program, you may have to prepare hard in all other aspects.
-> Try adding some relevant exp for 1 or 2 yrs at least.
-> If you have missed any Math pre-req in UG, then take some pre-MFE programs to complete that.
-> While importance of CFA to get admit is being debated highly, I would suggest you to go for it. Clear at least 2 levels of CFA before applying.
If you enter into some mediocre univ in US, in the present state you will find it next to impossible to find a job after graduation. Even if you come back to India, you will need some good brand in your resume to find a job.
So I will suggest you to prepare in all aspects to strengthen your profile and enter into some good universities. If I were you, I would even try to do my PG (MBA or ME in relevant fields in a good coll) and try to get some good score in my PG and then apply for MFE...
