Hello , this year i qualified to the IOI , so to get ready for that i think the best way is participating in contests but as everybody see the ioi style contests are so rare , so i decided to add an old contest (USACO , COCI , COI , etc...) every three or four days and participate on it.
so i'm going to invite you to join me and participate on those contests .
i will add the contests to Hackerrank , and i will post the time and the description here on codeforces .

the first contest will be held on Apr/19/2016 at 18 MSK , the contest's duration is 4 hours and the problems are from USACO 2012 February Contest there will be four problems 2 gold and 2 silver .
