Hello Codeforces community!

Right now, my team are training hard for ACM-ICPC World Finals 2017. It's the last World Final in my life!

However, while seeing various contests at Codeforces::Gym, I am really confused of which contests are appropriate to prepare for World Finals. Except past WF (there are few such contests), others seem to be unsuitable (regional contests, except NEERC, might be easier, while Petrozavosk Training rounds turn out to be deadly). Which kinds of contest do you use for training?

Beside that, I would like to know if there are training contests. I highly appreciate Codeforces weekly Training or NAIPC. I understand that doing virtual contests are adequate, but such contests attract more teams, therefore they reflect accurately where we are in the world!

Thank you very much and see you in World Finals!

You can try Codechef ICPC Preparatory Series. There is also a ranklist so you can track your position manually.

I may have slipped off Grand master a bit but still have the skill to train you :D

For WFs I recommend training on problemsets that consist in half of only ugly geometric problems and the rest somehow distributed between problems like "translate directly very chaotic statement into C++", some problems requiring backtracks filled with weird heuristics, some obvious problems requiring heavy library algorithms and one or at most two problems requiring some thinking :p.

Okay, maybe that was a little bit exaggerated ;p. But jokes aside, those mentioned types are really often featured with geoms heavily overrepresented. Translating words into code is my "favorite" type of problems.

    Why do they like geometry so much? Geometry is nice if you can reduce a problem that doesn't seem to have connection with geometry to some geometrical representation, like the convex hull trick DP optimization. But "hey, would you please rotate this weird 3D solid to fit this weird bag?" is very boring to me...
