This site currently includes about 4,100 olympiad problems and about 1,700 other problems. I have given solutions for about 2,300 Olympiad problems (and almost all the Putnam and AIME problems). My ultimate objective is to include a wide variety of interesting problems of all levels of difficulty. In general, I have no interest in pure bookwork problems.
Unfortunately, I have not had time to update it in the last year or two. Maybe later this year ...
Two features about the site are unusual. The first is that I strive for completeness. There are often many sites that give the last few years' problems for an olympiad, but this is usually the only site that gives all the problems. The second is that I try to put up solutions. Inevitably solutions will lag the problems, maybe by years!
