My current branch is a rural branch that is it is situated in a rural area of the district and mostly caters to the need of rural folks and helps in their financial inclusion

State Bank of India is the biggest bank of Indian and is owned by the Government of India. I have already got one promotion in the bank with a current package of around INR 10lacs

BOOTH
OXFORD
CAMBRIDGE
i will settle for
INSEAD
IMPERIAL
IE/ESADE

should i retake the exam or apply with this score

Ma'am
Thank you very much for your reply.
i have some supplementary questions. i would be grateful if you could answer them

1) is being above 28 years a disadvantage
2)with a score of 680 would it be pragmatic to pitch for the colleges i have mentioned
3)Ma'am i might not necessarily increase my score if i give a retest as i hardly get any time to prepare. Can my work ex in a government bank which has given me exposure to both corporate banking as well as an opportunity to work at the grass root level among the poorest of the poor where I am actively working towards the goal of financial inclusion by virtue ob being the branch head of a rural branch,in any way compensate for my score.
4) if the answer to the above question is negative, then please guide me as to which colleges would be suitable for me

Regards
