If your grades have been low and put you at risk of not being awarded an honours degree, there are several possible outcomes. There may be an opportunity to re-sit one or more exams, or re-take one or more modules. You should discuss this with your personal tutor, who will be able to advise and make arrangements.
If you ultimately fall below the 40% average grade required for a 3rd Class Honours degree you may be awarded an Ordinary/Unclassified degree. This is considered a lesser qualification than an honours degree but still counts as a graduation.
If you have passed some modules but not earned sufficient credits to graduate with honours, it may be possible to take an Exit Qualification - either a Graduate Certificate or Graduate Diploma, depending on the number of credits earned.
