Hello Aspirant,

Yes the attempt for JEE-Advance will definitely be deducted even if you are unable to appear in it or unable to qualify JEE-Main.

Let ma make you clear with an example,

see if you are going to pass your class 12th examinations in 2022 then you will be eligible for JEE-Advance 2022 and 2023 provided that you qualify JEE-Main 2022 and 2023 respectively. Now if you somehow don't appear for JEE-Advance 2022 then also your one allowed attempt will be deducted and then you will only be eligible for JEE-Advance 2023.

This is because maximum attempts allowed for JEE-Advance is 2 in 2 consecutive years, first attempt in the passing year of class 12th or equivalent examination and second attempt in very next year to that. Similarly for JEE-Main maximum attempts allowed for JEE-Main is 3 in 3 consecutive years, first attempt in the passing year of class 12th or equivalent examination and second attempt in very next year to that followed by third attempt in third year.
