Hey Nitu!

You would have received a mail when you first registered or applied for the entrance exam. Go through your inbox and search for that mail. From that mail you can recover details which will assist you in getting access to the form. And in case, if you are not able to locate the mail you should check your normal messages. From there also you may be able to get access to your form.

If you are still unable to get access to your form, then you may contact the helpdesk. You can get the number or email on their respective website. Do contact them and they will be able to assist you.
