**Update 2018.11.01**: [user:Rezwan.Arefin01,2018-11-01] made a very cool webapp which contains identical problemset, but with more usability. Thank you very much! [You can check it here.](http://codeforces.net/blog/entry/62898#comment-468763)↵


**Note: There was some updates in 2018.10.05.** See [here](https://codeforces.net/blog/entry/59422?#comment-462081) for changes!↵




Hello! APIO 2018 is near the end, and IOI 2018 is in this September. I hope you are preparing it well! ↵

I'm here to present my OI problem checklist : ↵

![scale=0.6](https://i.imgur.com/K25OVF6r.png)↵

I used this to train myself in IOI 2015~2016, and to train Korean IOI 2017 Team (probably 2018 too). For long it was in the "beta" phase, but I think it's now good enough to share!↵

This problemset contains about 300 ~ 400 hard and interesting problems, with appropriate judge links given. (If there is problem in judging, maybe [user:ojuz,2018-05-12] can help that..)↵

[Google Docs Link](https://docs.google.com/spreadsheets/d/1-kY6uiLOo1AKSBCSjbpGRBZbIldO_3dg6oTRKIJzT-g/edit?usp=sharing)↵

I hope this can help anyone preparing for future OIs, and a complete answer to the question "How to excel at IOI-style contests" :D
