Dear aspirant,

According to your question and taking into consideration that you want to know whether you can give jee mains in 2021 and considering you have given improvement exam in 2019 and so your final marks is this.

Your final marksheet is the 2019 one.Forget about what you got in 2018 and coming to your second part of question jee mains can be given only 3 times consecutively.

So you cannot give jee mains in 2021 as you have appeared for class 12th in 2018.
