if i am passed 2018 but i cant get good score i wish i am repeat my board these year then can i eligible for vit,srmjee etc??
Yes if you repeat your 12th these year and score good marks than you can study in some good colleges and also can apply for VIT and SRMJEE if you have a good score in those exams too and stand in a good rank or position than you will be eligible for studying in those university.
All it matters is if you can explain your 2 years gap and also if you can score really well in their exams.
All the best.
I hope it helps.!
