Not allowed to write my 2nd KCQ.

I was supposed to have completed my 2nd kcq's of 4 modules before the 30 April 2024 and I was not feeling well.Out of the 4 modules they could only extend my 2 modules and the other 2 modules I was told to re-register as the kcqs can't be extended.I tried to explain that I have to been well but they told me they can only accept hospital admission letter in order for me to write the 2 KCQs.My 1st KCQs I've passed them so well,they told me even if I get 100% on my 1st KCQs and final exam,I still need to re-register my modules .I mean why cant they calculate based on the percentages of the work submitted,but we must always accept when their classes are behind the KCQ as*****ts.
