is it necessary to appear in all 4 attempts of jee mains exam or only one attempt will work to get admission in any college of engineering???

Hello Aspirant,

No It is not necessary to appear for all 4 sessions of JEE-Main , this facility is provided so that if any candidate has scored less in any session then he/she can improve his/her score in further sessions without wasting an year, if you want you can appear only for 1 session or 2 sessions or as much as you want out of 4.

JEE-Main 2022 eligibility criteria is defined below :-

1--- Age criteria :- There is no age limit to appear in JEE-Main but note that there might be the age limit in any particular institution taking admission through JEE-Main score, so you should keep this thing in mind.

2--- Qualifying Examination :- To be eligible for JEE-Main one should have passed 10+2 examination with Physics, Mathematics as mandatory subjects along with one of the Chemistry/Biotechnology/Biology/ Technical Vocational subject from any of the recognized central or state board.

3--- Year of qualification :- For JEE-Main 2022 only those candidates who have passed Class 12 / equivalent examination in 2020, 2021 or 2022; or those who will be appearing in Class 12th / equivalent examination in 2022, would be eligible to appear.

So if you follow all above criterion then you are definitely eligible for JEE-Main.
