Until ABC 318, we used 8 problems per contest because there were many difficult tasks we wanted to use in ABCs. Since we have used most of them, from this ABC, we will use 7 problems per contest. The difficulty of problems A-F will not be changed. The range of difficulty of new problem Gs will be wider, some of them can be as easy as current problem Gs, while others can be as hard as current problem Exs. Please check the point values of each contest for more accurate estimation of difficulties. We are looking forward to your participation!
