Hello student,

YES, if you give the improvement exam in 2023 and if you will score more than 75% in class 12th in improvement exam in 2023, then you will be eligible to give JEE mains and then JEE advance examination. Furthermore, I would like to tell you that will be your last attempt in JEE advance in 2023 as every candidate is allowed to give JEE advnace two times only from the year of giving the class 12th exam. So you can give JEE advance exam in 2022 and in 2023 only. You can give JEE mains exam in 2022, 2023, and 2024 - 3 times

A candidate who has passed the Class 12th examination of the Board may re-appear for improvement of performance in one or more subjects in the main examination in the succeeding year only . So, you can give improvement exam in 2023.
