Hi

In 2020, qualifying cutoff for sc category was 50.1760245 and jee main 2021 expected qualifying cut off percentile is 50-55 percentile.

You can check the same at our page the link is provided below

So, with 51 percentile you hold a decent chance to qualify jee main but just qualifying jee main doesn't guarantee admission in any nit, as admission is solely on the basis of rank in jee main.

Your profile suggests that your home state is Punjab so you will be eligible for home state quota in nit jalandhar.

With 51 percentile

• your rank will be around 501270 - 563500 per our rank predictor at

  JEE Main Rank Predictor 2021 - Predict your JEE Main ...

Your sc rank will be around 40,000 .

I am extremely sorry to tell you but with above predicted rank you have a very low chance in NIT Jalandhar even under home state quota

For example,

In 6th round of josaa counselling 2020, closing rank for gender-neutral for sc category was 16543 sc  rank under home state in NIT Jalandhar and it was for Textile Technology (4 Years, Bachelor of Technology)

Above prediction is on the basis of past year data but  cut off/closing rank for colleges keeps changing every year depending upon many factors like number of students that appeared in the examination, difficulty level of the JEE main question paper for different shifts etc so
