InfinityDots MO files now available!

The InfinityDots MOs are our Mock IMO contests on AoPS. We have held two InfinityDots MOs so far with lots of participants and great feedback.

Today we have added the InfinityDots MO and MO 2 problems and solutions to our archive. Here’s a direct link to the folder. Also, while this is the English site, we’d also like to note that we have translated the problems into Thai; the Thai versions are now available in our archives too.

We invite readers who are interested in IMO-like contests to try these problems. Read more about our contests on AoPS here: InfinityDots MO, InfinityDots MO 2.

TMO 15

Hi,

During the past several days, the Thailand Mathematics Olympiad was held in Nakhon Ratchasima. In this post, we are sharing our solutions, along with some comments, to the problems in the competition. But since it’s always good to try solving problems yourself before reading the solution, we’ve attached the solution file at the end of this post and give the non-spoiler version of comments to each problem first.

Note that we use the difficulty rates as in our POTWs, that is, POSN Camp level is 1-2, TMO level is 1-3, October Camp is around 2-4, and IMO is around 3-5.
