Failed A Module But Have Enough Credits To Progress?

I have just finished my second year at KCL and have achieved 105 credits at level 5 plus another 15 credits of condoned fail. I achieved 135 credits in my first year at level 4. Ordinarily this would be enough to progress to my third year, however due to a submission error that I hadn't realised had happened I have ended up getting a 0 in a compulsory module (was also absent from my first exam due to other reasons I won't go into). King's define a compulsory module as a module that must be taken vs a core module as one that must be taken and passed according to their academic regs. As a result of this I have been given a UGCert and told I can't complete my studies. This exit award only validates my first year of study even though I have enough credits to get a UGDip for my second year. Is this a mistake, if not have I any grounds for an appeal over this decision. I am enrolled into 120 credits in my last year which, if passed will mean I have the full 360 credits for my honours degree.

You say you "have achieved 105 credits at level 5 plus another 15 credits of condoned fail". So, you have 120 credits at Level 5.

However, you also say that "due to a submission error that I hadn't realised had happened I have ended up getting a 0 in a compulsory module". So that means you don't have 120 credits at Level 5. Have I got that right?

How many credits was the compulsory module which you scored a 0 in worth? Was it assessed via exam, coursework, or a combination of the two? Were you given an opportunity to be reassessed? What happened during reassessment?

I have 120 credits in level 5 as I took on additional credit this year, both the failed module and additional were worth 15. Assessed via exam this was the resit.
