Look for a "Profile" or "Account Settings" section within the university application portal. Some universities allow you to edit basic information like your email address within the portal itself.

If you can't find an option to edit your email within the application portal, contact the university's admissions office directly. Explain that you entered the wrong email address during application and request a change to the correct email.

Be prepared to provide them with your application reference number, full name, and any other relevant details to verify your identity.

They might ask you to submit a request form or send an email with your correct details for verification.

Some universities might offer a "Forgot Password" option on their login page. If you can access this feature with your incorrect email address, it might allow you to reset the password and potentially update your email address during the password reset process. ( Note: This might not work in all cases, and it is best to prioritize contacting the admissions office directly.)

I hope it helps!
