I have given 12th exam in 2020 but not appeared in JEE advance in that year(2020) and planning to give in 2020, as my expectation is high I want CS in IIT(s) for this I need to have 2000 > rank . But if I fail can I drop for another year and plan for second drop and give JEE advance in 2022.

Now according to JEE advance brochure ( for me important point is listed below)

A candidate should have appeared for the Class XII (or equivalent) examination for the first time in either 2020 or 2021 with the subjects Physics, Chemistry and Mathematics. Candidates who had appeared in Class XII (or equivalent) examination, for the first time in 2019 or earlier, are NOT eligible to appear in JEE (Advanced) 2021
By appearance in Class XII (or equivalent) examination, it is meant that the board concerned declared the result of a particular candidate for that year irrespective of whether or not an examination was conducted. It will be considered as an appearance even if the result of a particular candidate got withheld
However, if the examination Board of Class XII (or equivalent) declared the results for the academic year 2018-19 after June 2019, then the candidates of that board who appeared for their Class XII exam in 2019 are also eligible to appear in JEE (Advanced) 2021, provided they meet all the other eligibility criteria. In case, the examination Board of Class XII (or equivalent) declared the results for the academic year 2018-19 before June 2019 but the result of a particular candidate was withheld, then the candidate will not be eligible to appear in JEE (Advanced) 2021

as you all know my result is declared on 15th July 2020 and due to lack of time I didn't give JEE advance 2020 that year(which was held on end of sept)

now according to brochure it clearly said if Declared the results for the academic year 2018-19 after June 2019, then the candidates of that board who appeared for their Class XII exam in 2019 are also eligible to appear in JEE (Advanced) 2021

IF we change the year from 2018-19 to 2019-20 and JUNE 2019 to JUNE 2020, so I am too eligible for JEE advance 2022

It sounds like you have a lot on your mind regarding your JEE Advanced eligibility and your plans for pursuing Computer Science at an IIT. Let’s break this down step by step to clarify your situation and options.

Understanding Your Eligibility for JEE Advanced

From what you've shared, you completed your Class XII exams in 2020, and your results were declared on July 15, 2020. According to the JEE Advanced brochure, eligibility hinges on when you first appeared for your Class XII exams and when the results were declared. Since your results were declared after June 2020, you fall into a unique category.

Key Points from the Brochure

• A candidate must have appeared for the Class XII examination for the first time in 2020 or 2021.
• Your result being declared after June 2020 means you are considered to have appeared for the exam in that year.
• Eligibility is also contingent on meeting other criteria, such as subject requirements (Physics, Chemistry, and Mathematics).

Since your result was declared in July 2020, you are indeed eligible to appear for JEE Advanced in 2022, provided you meet all other requirements. This means you can plan to take the exam again next year if you do not achieve the desired rank this time around.

Considering a Second Attempt

Dropping a year to prepare for JEE Advanced is a common path for many students aiming for top ranks. Here are some factors to consider:

Pros of Taking a Drop Year

• Focused Preparation: A dedicated year can allow you to strengthen your concepts and improve your problem-solving skills.
• Time Management: You can create a study schedule that suits your learning pace without the pressure of other academic commitments.
• Increased Confidence: With more preparation, you may feel more confident going into the exam.

Cons of Taking a Drop Year

• Pressure: The pressure to perform well can be intense, especially if you are aiming for a specific rank.
• Uncertainty: There’s always a risk that despite your efforts, the outcome may not meet your expectations.
• Social Considerations: You might feel out of sync with peers who are moving forward with their education.

Strategizing for Success

If you decide to take the JEE Advanced in 2022, here are some strategies to maximize your chances:

• Structured Study Plan: Create a detailed study plan that allocates time for each subject and topic.
• Mock Tests: Regularly take mock tests to familiarize yourself with the exam format and time constraints.
• Seek Guidance: Consider joining coaching classes or study groups to benefit from shared knowledge and resources.
• Health and Well-being: Don’t forget to take care of your physical and mental health during this preparation period.

In summary, you are eligible to appear for JEE Advanced in 2022, and if you feel that you need more time to prepare, taking a drop year can be a viable option. Just ensure that you approach it with a clear plan and the right mindset. Good luck with your preparations!
