For those Diploma holders of Maharashtra who are desirous of seeking lateral admission directly into second year of engineering college, there is no entrance exam. Admissions are based on marks obtained in Diploma exam.
Best wishes to you.

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.

GOOD LUCK!
