I think that reading those pages within the forum are of great use to see how other people fare and what to roughly expect yourself, but it's super important not to get worked up on these figures. The real UCAT is now not too far distant and hence in this time, it is essential to focus on your own practice and work on ways to improve your own score. The worst thing now would be to doubt yourself and the efforts which you have put in all this time - just believe in yourself and your efforts. I understand that these numbers can affect you mentally, but if you try your best, you are far more likely to achieve what you are hoping for than if you get caught up with these statistics!!
Hope that's of some reassurance and help!
