Hi

You should choose 2019 as your passing year.

This is because,

Improvement examination is just an examination to improve your percentage in your class 12th examination and improvement examination is given by only students who have already passed class 12th so although  you have appeared for improvement examination in 2020 your passing year still remains 2019.

And now that it is your drop year do prepare well for your JEE mains 2021 examination

You have limited time left for your jee examination I'll suggest you to focus on your preparation, go through chapters well, practice questions and revise, go through mock test paper sample papers and previous year question papers as it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination.

To prepare well you can go for our jee program at the convenience of your home, the link for the same is provided below
