Whether you will get admission in NIT surathkal or not will depend on your rank in JEE Mains and not the marks.

Once NTA release the Jan result (only percentile will be released now and the Ranks will be released after JEE Main April), you will be able to calculate your expected rank.

Just to check the last year's cutoff ranks for NIT Surathkal and other NITs/IITs, kindly use the following link:

According to last year marks vs rank scenario, your rank will be upwards of 1 lakh.

So it will be very difficult for you to grab a seat in NIT Surathkal, even under Home State quota. If you belong to a reserved quota , you may have an outside chance of getting a seat.

However, the results are still not out, so it is too early to predict the rank , since the difficulty levels of papers may vary year to year.
