Problem 22/23?: This is another interesting polynomial problem. You will regret it after the competition is over because you found a really simple solution but didn't use it and gave up.

Problem 24: This is a geometry problem which nobody will get. No, you're not getting it. You know what? People seem to be getting these problems too often. Next year, hyperbolic IMO level geometry problem which everyone guesses correctly because there was a large prime and/or relevant square root in the numerator or denominator.

Problem 25: This complex number problem is actually really easy, you just had no idea because you were overwhelmed during the competition and didn't look at all the problems.
