A very late post, but since the celebration was memorable for me I want to write it down, as the phrase goes in Spanish "más vale tarde que nunca". On the night of the 15th we went to the university to celebrate "El Grito". I actually missed "El Grito" as I wasn't expecting it to be at 11pm (since 11pm is midnight in Mexico City), I was expecting it at midnight. The main motivator for me to go was to show the celebration to Yuliia.

On the 16th, my mom had a big party at home. It was very fun. We played several games, we danced and at the end we sang karaoke. There was a lot of really tasty Mexican food.
It was a really fun night.

This year Mexico got to be the host of the IberoAmerican Mathematical Olympiad which would be held in Querétaro. As a coordinator, I would have to be in San Miguel de Allende the first days of the competition, since I had knowledge of the exam we had to be isolated from Querétaro.

Yuliia and I got to San Miguel de Allende on the 18th. The next day, we walked around. The town is very beautiful. We had a really good time. The hotel ("El Atascadero") was wonderful, a beautiful room, a beautiful building, a nice swimming pool, great service and fantastic food. I enjoyed all the meals there.
After realizing they didn't require me on the 20th, I took Yuliia to Guanajuato, my favorite city. I have always dreamed of taking a girl to Guanajuato with me and now it came true. I had a great time walking in the town, walking up to the Pipila. I also saw something I hadn't seen before, which was the Quijote museum, a really cool museum with art relating to Quijote.
In San Miguel, Yuliia and I had a good time swimming and relaxing in the beautiful town. I had little to do as my only job was to create a grading scheme for the problem I would grade (problem 2), which was a day's worth of work.

Yuliia left on the 22, I went with her to the airport (in Mexico City), then I went to Querétaro. Because of accompanying Yuliia to the airport, I didn't get to sleep (we left at 2am for the airport, got there at 8pm and I got to the hotel in Querétaro at 1pm).

That night in Querétaro I started grading. The next day it was time to coordinate (this is where you discuss the grades with the country leaders). The whole day was full of work. In a span of 24 hours I worked 22. It was very fun. I was happy to see many solutions to the problem. A translation to English of the exam can be found here. A sad thing about the test is that problem 5 had been posted in mathlinks a month before, hence the question wasn't quite original.

The winner of the Olympiad was Perú, beating Brazil by 1 point. Spain was third, followed by Argentina and Mexico. While I am not that happy with Mexico getting fifth place, I am happy that Memo (a student from Chihuahua) got a gold medal. It is the first time that a student I helped prepare gets a gold medal in the Ibero.

In Querétaro I had a very good time talking with David, Joshua, Bernardo and others. I also had a good time beating everybody in Ping Pong.
I walked downtown with David and enjoyed it. Querétaro seems to be a very lively town. There was a plaza with a mini-orchestra playing tango, a plaza with people dancing capoeira and other plazas with other things. Very pleasant night.

The time in San Miguel/Querétaro was wonderful. I had a very relaxing time where I could talk to good friends, share beautiful places with Yuliia, get inspired mathematically and eat magnificently. I am very happy to be a part of the Ibero.
