Dear applicant,

No need to worry. Try once by cleaning browser history, cache files from the browser you`re using. If it still doesn`t work the process is as follows, you just need to visit the official examination portal. Just contact the exam authorities. State your troubles to them, you might need to drop a mail with required documents attached. Remember to stick to the given deadlines. Please stay updated to the counselling schedule, so that you do not miss any good opportunity and keep your documents ready and up to date.

Hope it helps.

All the best for your future endeavours!
