See, the National Testing agency (NTA) and the IITs have collectively decided to scrape the minimum 75% criteria for Joint Entrance Examination Main and Advances for the year 2022. So, if you have 71%, you can give JEE in 2022, but since the circular of 2023 is not yet release, no one can tell if you can appear for the same the next year. So, keep preparing accordingly.

Hope I have answered your question. All the best!
