Ok, so I've sent my UCAS application off, but when i was filling in my qualifications I couldn't find my GCSE certificates to input the correct grades, although I knew what i had got, i later found my certificates and notices that i'd put a wrong GCSE grade on my application. Is this a massive problem? How do i correct it? I only sent my application on the 22nd so is it not too late to email my choices? or do i have to contact UCAS aswell? Thanks for any help!
