I'm actually not that surprised. Maths Olympiads IME have always been 80% preparation, 20% skill - if not more heavily tuned to preparation. It was all about solving as many problems as possible ahead of the papers, and having a good short term memory. Since Olympiads are for kids, the amount of actual fundamental mathematical theorems required is actually not that great. Sounds perfect for a GPT model, with lots of input training data (problem books and solutions).
