These notes
- may be useful
- to the students who would like to have a look at some of the past RMO problems, in order to have an idea of the notions/topics involved, and/or to have a glimpse before getting started, or just curious about it,
- to the students, who would like to prepare and would like to have the relevant questions organized across the topics and sub-topics,
- also aim
- to spread awareness for the Mathematics Olympiad programme in India, conducted by the Homi Bhabha Centre for Science Education (HBCSE), which is the only programme in India leading to participation in the following International Mathematical Olympiads — IMO, APMO, EGMO. No other contests are recognized.
- to provide resources to the students who may not have access to introductory/preparatory materials related to Mathematics Olympiad.
