Kattis is an online programming problem archive that gives you points for each problem you solve in relation to how difficult the problem is. It then aggregates the total points of people within a university, and within a country, based on an adjusted sum of the total points of all members of each group.
DCU, the university I attend, is now in the top 50 in the world on Kattis, and Ireland is in the top 30 countries there.
I recently wrote a piece on cpssd.net about how much of Ireland's score on is contributed by myself and my coursemates. It turns out that more than 33% of the score of Ireland comes from my points 🎺
You should read the piece here.
