Hi everybody! I am a student and preparing for my third ACM-ICPC season.

Recently, I found a site ICPC Live Archive, which contains many problems from different regionals competitions of past years. I solved some problems from here, but some of them are very easy for me, and some are very difficult. I think, that these problems more suitable for team trainigs, not individual (I haven't a stable team). Also, I solve a problems from school olympiads (USACO, National OI's and etc). In my opinion, these problems more suitable for individual trainings. Also, many of them "less standard", then student problems.

I want to know, how many people solve school problems for preparing to ACM-ICPC? And which problems are more suitable for it?

Sorry for my bad English.
