I was registering for under graduation. During registration i could not write my surname in the "surname" column and in the 12th total marks i have written 600 instead of 500 marks by mistake.. I realised that by mistake i wrote 600 marks during registration.. So please sir cancel my registration before the last date of registration so i can refill my online form as it is my only option. Please.
