Dear Harshit, you haven't mentioned which programme you have applied for. Irrespective of the programme that you have applied for, unfortunately Christ University application process doesn't have a correction window unlike other entrance examinations. So, you will have to fill in a new application all together. So, if the error is as minor as pincode, you can leave the application the way it is cos it doesn't affect your merit. But if you have entered other details like Date of Birth, Category and Gender wrong, you need to fill in a new application form all together cos it will affect your merit.
