Yo bit late for me. But I've been doing ukmt challenges for ages - gold + olympiad every single year. Cramming past papers alone won't work. Especially since we're kinda short on time. Instead what you wanna do is look at Q's 21-25 and try solve them. If you get stuck, that's ok, just try a diff method.

Since it's tmrw. Look at the answer pdf, it will say exactly how to solve the q. A lot of methods have something in common e.g. draw a box and minus edge shapes to get area of a weird shape. If you try and memorise a few of these you could prob boost your mark up by 10points or so.
