Will universities know I redid a year?

Yeah so basically I was supposed to finish my IB diploma in 2012 but I only finished it this year. The reason to this is that in January 2012 I was forced to drop out due to illness four months prior to my IB exams and hence I did not take the examinations in 2012 but only completed them this year.
I have good grades and know I want to apply to Med school for 2014 Entry and I was wondering if universities in the UK will know if I've redone a year (half a year technically) because that would surely disadvantage my application to Med School?

Thanks in Advance

You will have to enter all exams and dates onto the form so they will know. Resitting due to illness wouldn't be viewed in the same way as resitting due to failure, though, and the reasons would be put in your reference.

But I only did exams in 2013 and not in 2012. How would they know I'm not just an ordinary student completing his exams in 2013.
In the IB we don't have any As, only final exams at the end of our third year.

Because your reference will explain your circumstances.

If it was for medical reasons, why on earth do you want to try and hide it?

Aha okay. But are you forced to do this, because I could just ask my reference teacher to not mention it.
I don't want to do anything illegal!

You also put your GCSE results down, so they'd see you did your GCSE's in 2010 (or whenever you sat them), but finished your IB in 2013. They'd basically see that you've got more years between getting your GCSEs and your IB than you usually would have.

Because many universities don't accept extenuating circumstances for Medicine, including my top choice --- UCL.

If they find out you have lied on any part of your application, they can withdraw the offer. Honesty is probably a quality universities like in Med Students. They won't look down on resits due to illness, so it shouldn't cause problems for your application.

I don't have GCSE's. I live in Denmark.

Where does it say that? It doesn't even make sense, they want the best applicants, not just those who were lucky enough to not have medical problems.

They will. Many universities don't accept extenuating circumstances for Medicine, including my top choice --- UCL.

UCL says this:
"Students who need to resit exams in Years 12 and 13 in order to achieve the required grades may struggle subsequently on our programme. Resits of January exams the following June are permitted, but we would suggest that candidates who need to resit examinations in order to achieve the required grades may not be well-prepared for our programme."

I think it's really unfair though as I have a good reason
