im interested in comencing my LLM studies in UK but find myself between a hard place and a rock. I was doing very well on my third year LLB when suddenly i was diagnose with diabeties. due to being unable to regulate it, i ended up in a coma which resulted me missing my last two final exams. prior to this i was predicted a 1st, however as a result of the illness: i was awarded an ordinary degree. i did desparatly ask for a chance to repeat my last year but was unsuccessful.

therefore, due to my dilema, im asking for any advise on how to proceed. any suggestion is welcomed

That was a terrible experience and You have came through it.
In my opinion, You deserve a place in any LLM more than most of people applying.
It's hard to say anything since I don't know Your overall situation, but from experience I can tell Yoy two things:
1) GPA (or Your place in group etc) is important but not crucial. With other conditions met easily (or better than required) You'll easily be accepted to most of Unis within the top15 (maybe the top5 or so we'll have some issues with it but there's more into it than just ranking).
2) Statement of Purpose (or whatever They call it) might be a good way of explaining the situation. I guess it won't be that easy but You can at least think about.

i think that some reference letters would be very welcomed (either academic or professional)
good luck!

As I recall (and without returning to the forms to confirm it), there is a field in most application forms to write about special considerations. You might consider using the opportunity to explain how your result was affected by your medical condition and why it is not an accurate measure of your abilities.

In addition, if you were diagnosed during your final academic year and were unable to regulate your condition, you should be able to prove (using medical records and academic transcripts) that the change in your performance and your diagnosis occurred roughly at the same time. You also could consider submitting specific records of your treatment for the period when you were in a diabetic coma and the dates of the exams you missed as a result.

Good luck!
