So I took my AS maths in year 11... I decided to retake the modules to try and get 100% UMS. I didn't tell any teachers at my college that I had already taken AS Maths. I have been entered in for C1, C2 and M1 again this year but IDK how retaking works. I haven't specified that its a retake. Will edexcel automatically overwrite my marks and grade or do I have to specify that I am retaking exams that I took last year!? I'm hoping it automatically overwrites any previous exam results but if anyone know please tell me!
