Hi,

Mock seat allocation helps the candidate to give their preferences of institute/branch and change them accordingly after mock seat allotment, if they wish to. There are chances that you might get seat in NIT, Surathkal in Civil Engineering but it is not guaranteed. If you change the preferences before the last date then your actual seat allotment might vary. There are 7 rounds of counselling in JEE mains qualifying students for admission. If you got NIT surathkal in consecutive 3 mock round and if you get it in in the third round of mock round also then it is confirmed that you will get NIT surathkal for your CIvIL engineering course of study.

Hope this helps

Wish you luck
