dear aspirant;

Cut-off marks are relative. They totally depend on the pattern of paper and ,of course,how the students attempted the question paper.CSE branch opens somewhere at 530 OC and it closed at roughly 750. Mech opened at 2249(its my rank so I could give the perfect figure) and closed at 3008 in open category. JEE MAIN will be conducted mostly on first sunday of April and JEE ADVANCED will be conducted on 3rd sunday of May. The JEE MAIN is entirely conducted by CBSE generally with the help of an NIT. JEE ADVANCED will be conducted by one of the older IIT’s(JEE ADVANCED 2016 was conducted by IITG and 2015 by IITB). The seat allocation process is entirely conducted by JOSAA both IIT’s and NIT’s combined.

Best of luck!

NIT Silchar takes admission through JEE Main. You need to score around 145 marks under general category in other state quota. Cut off varies branches wise.

JEE Advanced maximum are not defined :

Maximum Marks vary every year like below:

 2017- 366

2016- 372

2015 - 504

2014 - 360

So, it is difficult to predict marks as exam pattern and marks change every year but you should score more than 50% marks to get good branch in Top IITs.
