my jee mains mark is 94 % then i get admission in nit gao?

Hello,

Your question is not quite clear assuming that it is 94 percentile your overall expected rank will be around 52140. And the formula is (100-your total percentile)*869010/100

where the total number of candidates appeared in JEE main January session is 869010.

You have not mentioned your Category assuming that you belong to general category considering previous year cut off you may not get seat in NIT, Goa unless you belong to Goa state. You need to secure a rank below 1500 if you belong to general category and in between 2000-5000 if you belong to reserved category. Cut off may increase or decrease depending on number of candidates appeared, difficulty of exam and number of seats available.
