Dear Vishu, the year gap will not affect your future because you had medical issues. You can appear for JEE Mains 2020 and secure a seat and take admission. During placements, there will be questions asked and so keep all your Medical documents intact. It's not that they would want to check it but it is just for your justification. But for now, your focus should remain JEE Mains 2020 and you can cross that ship when time comes. During placements, what matters is your aggregate in your Bachelors and also your performance in the Interview.

Hello dear student,

I hope you are aware of the eligibility criteria for her mains 2020 that is candidate should have passed class 12 or qualifying the exam in 2018 or 2019. And as you have to drop the first in 2018 that means you have qualified class 12 in 2018 .  Dear student may be you have dropped for 2 years but don't worry that is not going to harm you anywhere in your future. So stay calm and prepare for your exam . I hope this was helpful

Best wishes
