What should be marks in mains for good nit or coep????

Hi Aspirant,
To be eligible for the top NIT's or COE,Pune,try to score more than 170 marks in JEE Mains.
the cutoff for COE,Pune is usually around this range with branches like CSE and mechanical having cutoffs more than 180.
For getting a seat in top NIT's,also you have to score in the same range or even higher.A score of 180 approx can prove to be good enough.
Hope this helps.

well it depends on your category your home state the NIT and also the course in which you are interested so considering all these factors closing rank very get greatly and you cannot tell you precisely that how much marks should score because marks vs rank where is every year it depends on the difficulty level of the question paper and the whole batch for all so I must tell you that you should check out the previous year closing rank of various NIT under different categories of your choice for your course of interest link is provided below
