U can give Jee mains entrance exam for 3 consecutive years including your 12appearing year. If u passed your 12in 2017 then u can give exam in 2017 2018 and 2019 not in2020

No you are eligible to give jee mains only in 2018 and 2019 As you have cleared your 12th boards exams in the year 2017.But i will auggest you to prepare hard for jee mains 2018.As you have already dropped one year,you need to make full effort to get good college this year.Wasting one year more will be of no benifit.Plan and prepare from your ncert books.Solve previous years questions for practice and to enhance your skills.
