Hello aspirant,

It does not affect your JEE mains and JEE Advance attempts form class 12th. It is the class 12th from which the attempts of JEE mains and JEE advance are counted. Also, every candidate are allowed to give JEE mains for 3 consecutive times and JEE advance 2 consecutive times from the year of passing of class 12th. Now, since you have mentioned that you have passed class 12th in 2021, then you can give JEE mains (for 3 consecutive years) uptill 2023 (counting from 2021) and JEE advance (For 2 consecutive times) uptill 2022 (counted from 2021). therefore, it concludes that you can only give JEE mains in 2023 and not jee advance.

further, since you are an JEE aspirant, below are some of the best preparation strategy that I would like to give it to you :

Prepare A Well-laid Plan

Draft a daily schedule.

Prioritize the topics that require more time and relevant to the subject.

Stick to the routine and pay special attention to problems.

Get Hold Of The Syllabus

Manage your time effectively

Understand Basic Concepts

Before delving into JEE preparations, know the JEE syllabus and understand the basic concepts present in the syllabus.

I hope that this will help.

See, you can give JEE Advanced only two times, in which your first time is automatically counted in the year in which you have completed you class XII, and next is the further year.

So, if you have passed your class XIIth examination in 2021 and have given the exam once, then you can give JEE Advanced only now in 2022, while you can give JEE Main in 2022 as well as 2023.

So, in 2023 you are not eligible for JEE Advanced, but are eligible for JEE Main. All the best!
