Hello, Aspirant..

The CBSE will disclose the JEE Main 2020 results, as well as the candidates' category rank and All India Rank.

The JEE Main 2020 cutoff for NIT Surathkal is determined by the All India Rank.

However, you can look at previous year's cutoffs to get a sense of what to expect this year.

From the above link, you may view the previous year cut off for NIT Surathkal for home state as well as other state quota for each branch.
