The National Testing Agency (NTA) has clarified the eligibility criteria for the JEE Main 2025. According to the official notification, candidates who have passed Class 12 in 2023, 2024, or are appearing in 2025 are eligible to appear for JEE Main 2025.   Thus since you are giving your Class 12th board exams in 2024-25 you are eligible for applying to the JEE Main 2025.

Few things to Remember:

Minimum Marks: Even though the percentage marks for taking up the JEE Main exam has no barrier, the candidate will be eligible to get admission into the IITs, NITs, or IIITs if he has secured a minimum percentage of marks in class 12.

Subject Combination: Physics, Chemistry, and Mathematics at the Class 12 level only must have been done.

Make sure you have all the qualifications and also follow the guidelines that the NTA has issued for getting qualified in JEE Main 2025.
