Hi everyone :)
If you have proper and prior experience, could you give some advices in preparation for the IOI? On what should my concentration be to do well?
If probably you can't give any advice because these questions are too general I put some questions below.
- How many hours did you prepare everyday to show your best on the IOI?
- What type of problems did you solve?
- What resources did you use?
- Should I do some math stuff?
- How to learn to solve problems which need a lot of observations, concepts?
Thank you so much!
