Hlo aspirant!

Since you have got 82.98 percentile your category rank will be somewhere above 1.5 lakhs and since you have ews category , your category rank will be somewhere between 27,000-28000. From the previous year cut offs of NIT silchar chances of your admission there are a bit low , but since you belong to the home state category you should definitely try for admission . I would recommend you to participate in the counselling till the last rounds , since you might get a seat their in the last rounds of counselling.

I wish you All the very best!

Hope my answer helps!
