Colleges in Pune

First of all I didn't understand your question, I mean if you are a diploma holder with average 50% marks and have secured a good rank around 50 then you can definitely take admission in KGEC, having maths or not doesn't matters, JELET is basically a exam through which students of diploma engineers can take admission into B.Tech colleges in West Bengal. So, if you are already completed Diploma or in last year then start preparing for it.
GOOD LUCK!

Yes , chances are there according to last year cutoff but sureity is not there. He may or may not get also.

He/she may get IIIT Bangalore in ECE dual degree at this rank. Last year the cutoff was 170 / 360 for this course, that means rank was near to 16 K. So chances are there.
