Hi aspirant,

You got 122 in Nata 2020 & 83% in your board exam. Yes, you have descent chances to get a seat in JJ college.

Minimum Jee paper 2 marks required is 80 out of 200 as well as 50% for general candidates. For Sc/St candidates it is 45%.

The candidate must have 50%+ in their board exam with PCM combination.

So, you have enough chances.

All the best !!
