These notes may be useful

• to the students who would like to have a look at some of the past RMO problem before getting started, or just curious about it.

• as a reference, to anyone who would like to provide guidance to students, and is eager to do so as soon as having the relevant questions across the topics and sub-topics available in an organized form.
