I'm from Azerbaijan and I qualified for IOI this year. It is off from topic, but we can't win medal for 5 years. I'm in 8-th grade, so there are 3 years which I'm eligible participate for IOI in future. But I want to win medal this year, I'm working very hard for that (almost all day)! However, I learned many new topics last in 2 month, but I think I'm not doing that in efficient way.
I kindly ask your help. I'm sure if you share some good stuff, not only me, many people will gain help from that :)
Thanks in advance!
