Medicine MMI next Wednesday HELP!

Hi! My QUB interview is next Wednesday and I was wondering what you need to know about the NI healthcare system because it's different to the NHS. Do we need to research it in depth or will surface level knowledge be alright?

Even if they might give you all the information in my answer I bring in extra knowledge and statistics. When practising so far I normally link it back to the NHS or statistics in England. Would I be OK with continuing to use those or do I have to research completely new statistics specific to the HSC and NI.
