Hello aspirants

you can't  give the exam. Even though there is no age limit As per NTA , applicants can appear in JEE Main for three consecutive years from passing class 12th. So, if an applicant passes their class 12th in 2022, they can appear for JEE Main in 2022, 2023, and 2024

Here are some eligibility instruction

• Candidates who have passed 12th class or equivalent exam in 2020 or 2021 (not before 2019) are eligible to apply for this exam.
• If candidates have appeared in a 12th or equivalent exam in 2019 but did not cleared in 2019, but passed in 2020 are not eligible to apply.
• Candidates who have passed 12th exams in 2019 or before or appearing in 2023 or later exams are not eligible to apply for JEE Main 2022.
• If candidates qualify 12th exam in 2021 & appear for improvement in 2022 for one or few subjects, then top 20 percentile cut-off for 2021 will be considered.
• However, if a candidate write all the subjects in 2022, then the best of the two performances will be considered.
• Candidates also note down that for the percentile system, total marks obtained in all the five subjects of mark sheet are required for JEE Main and JEE Advanced.

Hope this Helps
