給你看下IMC難度介紹，也就是AIME中段難度

The International Mathematical Competition (IMC) for University Students is a challenging contest, and its problems are generally considered to be at the intermediate to advanced levels of difficulty on the Art of Problem Solving (AoPS) scale. Specifically, the IMC problems would fall within the 3-6 range on the AoPS competition difficulty scale, possibly even reaching into the 5-7 range for some of the more difficult problems.
