Hey,

NTA will release the rank only after the April session. Now, you haven't mentioned your category, so I may not be able to give you the perfect answer, but for general category candidate, a score of 120 can get you a rank between 21,000-25,000 and your percentile may be around 97.49-97.69.

You can use our JEE rank predictor and use your category and other details to get accurate percentile:

Hope this helps!
