UKMT Specials Thoughts

You will have around $4 - 14$ days to solve the special (depending on the difficulty).

Last solution submission time will always be $3:00$pm. On weekdays, I'll post the solution at $4:00$pm, weekends, I'll post the solution at $3:30$pm.

All the problems have been taken from my UKMT database (took me $\frac{3}{2}$ days to complete it!)

If you want the official database, go to their website:

UKMT Solo Competitions

The recent ones are free, but the older ones, you have to buy!

As for commenting, commenting is strictly restricted to my comments or reports - general questions about one of the questions can be posted in the special's chat space.

Update: For BMO solutions, I will be looking through solutions by video on this website:

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
