Graduation

Hello,

I am currently studying towards a diploma in computing and IT at the Open University. I only have one module left to complete, but the diploma is supposed to take two years. I had to repeat one module from the first year, and while I was getting good marks, I missed the cut off exam due to some unforeseen circumstances. Unfortunately, the university refused to let me resit the exam, which was very disappointing for me as a mature student who really wants to graduate.
I would like to attend the graduation ceremony this year, even if I don't receive my certificate. However, I'm not sure if the university will allow me to do so without completing all of the modules. Additionally, I will be traveling to another country next year and won't be able to attend the ceremony then.

Does anyone know if the university will let me attend the graduation ceremony even though I still have one module left to complete?
