Kind regards.

My country (Peru) will participate for the first time in the IOI this year, and I am training schoolchildren with high chances of qualifying for the Olympiad.

Clearly there is a gap between the national Olympics at the Latin American level and the IOI. What I have done so far is choose Olympics problems such as the JOI, CCC, BOI, etc. and solve them in class as well as teaching algorithms from the IOI syllabus.

I don't have much experience (and I'm not a grandmaster) so I would like some advice on how they train in other countries or what I should do with my students.
