PRIME

The VCSMS Program for Inducing Mathematical Excellence aimed to prepare for the qualifying round of the Philippine Mathematical Olympiad. I conducted the program in our school for the years 2016 and 2017. Materials here include lecture notes, past PMO problems sorted by category, and solutions.
