Hello Jasthi..

You should expect your percentile to be in the region of 96.6-96.9% if you get 108 out of 300 points. Your general rank, or AIR (All India Rank), should be between 28000 and 35000 with this percentage.

This forecast is based on data from the prior year. According to the previous year's cutoff, this score qualifies you for the exam and allows you to participate in JOSSA counselling, but your chances of getting a seat in one of the top NITs appear to be slim.

I hope this information helps.

All the best.
