Bhavika,

I'm sorry to inform you but you can't change your email address during correction window. It's your 1st basic credential that you provide to NEET authorities during registration of your application. So, you can't change it during correction window. But don't worry. Even if it's wrongly provided, you have the provided phone number correct. They'll send every notification to both phone number and email address. So, don't worry much.

Hope this helps and all the best!
