hello prakash,i would suggest you to send a mail stating your problem to the exam conroller and am sure they will provide you with a solution for your problem, but dont worry about it so much now and prepare well for your exam,i wish you a very good luck.

Hello , Prakash

Yeah! You can log in to your application form for correction before the deadline date of the application!

You can make corrections in personal detail,image correction etc.

After making corrections you can check you application status by again loging in.

Hope this will help you!

All the best
