OK. Brighton's General Examination and Assessment Regulations for Taught Courses (GEAR) are available
here.
The phrase "at the discretion of the Examination Board" appears a
lot, which makes the document effectively worthless. They might as well say, "We'll only adhere to these regulations if we want to."
I have a couple of questions about the compulsory module which you have now failed twice:
• How many credits was it worth? Was it more than 20?
• Was it a year two module? Or did you initially fail it in year one, and were were allowed to trail the credits via a conditional progression into the year two?
It is worth noting that regulation 5.2 (which falls within section 5, Repeat) includes this clause:
"vi. one further referral may be permitted
if a repeated module is failed (unless the student has reached the maximum number of assessment attempts permitted under the regulations)."
So that means you can fail a module, repeat it and fail again, and
still have "one further referral". Unfortunately it continues "...
may be permitted...". So this is "at the discretion of the Course Examination Board".
Have you followed the advice of the Students' Union and contacted the Additional Consideration Office? (Details of how to make a full request for additional consideration are provided in section 5.6 of GEAR.)
