# Contests

Most of the past contest problems are from Nathanael Joshua Balete, unless otherwise stated. My contest reflections are at the bottom of the page.

## PMO

Here are past problems for the Philippine Mathematical Olympiad. This is everything available on the PMO website, and some files that aren’t; I’m linking everything so it’s easier to use. Credit for everything that aren’t my write-ups rests with PMO. Some scattered solutions to pre-2016 problems are in the PRIME page; I might turn these to a write-up later.

You can view the LaTeX sources of the write-ups.

## Sipnayan

Past problems for Sipnayan, organized by the Ateneo Mathematical Society. Prior to 2015 there was no division between junior and senior high. The official page is AMS Sipnayan on Facebook.

## Reflections

I wrote reflections for the math contests I joined from 2016 to 2018, which covers the end of tenth grade until I graduated from high school. They consist mostly of talking about what happened, and some thoughts on the problems. I have reflections for programming contests too.
