any date to verify mail

It has to be done within the last date of submission of application form.I would suggest you to try verifying the email after midnight since the load on the servers by then will be less. Try this, if you still didnt get the verification mail, kindly contact me!

where to verify mail please provind me step by step process 

Yashwanth,While filling up the application form, you will have to verify your email address and mobile number. Mobile number verification is easy and email verification is taking more time.For the email verification, I would suggest you to open your application form window in one tab of browser and your email inbox in another tab. Click on Verify email and then chck your mail box whether you have received OTP or not. If not, refresh the page. If still you have not received, go to the application window and click on re-send the OTP. wait for like 5-10 min and you will receive the OTP. enter the OTP in the box and verify.Since, i tried these steps and it worked for me. I would suggest you to try these steps at after 11 PM. When you can easily verify the steps.all the best!

After submission there is no option of verification of mail in it

Yaswanth, See you must be able to see the application form status as "Your application is under Scrutiny"So, you will be notified within a day or two regarding the same whether your email has been verified. then you can verify your email.

Rajeev, can you tell me the steps to verify my email otp after submission of gate application because I am noot being shown any option to edit the application.plz help

Aayush, You will not be able to verify it for now. Till the authorities ask you to verify it again. Kindly wait for their mail regarding the email verification. After getting the mail from the GATE authorities only you will be able to verify your email.Also, from tomorrow onwards, the correction facility of application form is opening, so you will be able to verify it from tomorrow onwards by logging into your account.

I have paid the amount but have not received any confirmation.Also there was some problem with the verification of the email id .Can I get the refund? Please let me know as to what can be done.
