I hope you are going well.
I found answers to your problem from my cousion’s life experience. She is a MBBS student. She too had many backs in MBBS and was two years behind but her fate changed, when she prepared again for all her supplys and scored the highest.
Sometimes we focus only at our present circumstance, we get a lot worry about them. Think of your life,the moment when you gonna pass out from IIT Delhi,having a job in your hand. clearing exams is ni big deal, if you can clear IIT JEE exam, so what in this exams.
