Today I planned to solve some 1300 and 1400 rated problems, I came across a problem that is rated 1300 but it was way easy to be tagged as *1300, is this a mistake or what??
Problem : The Bento Box Adventure

this is a common problem with old tasks, check this problem: IQ test
But this problem from 2024, not that old.
idk what the hell is wrong with this problem
Yes, and this problem is from 2024 ICPC regional contest
That's probably the reason its rating is so high — it was an unrated contest so less people with low rating participated and solved it
Yeah, but all the NT 1600 ones I saw were very easy.
I think NT (and generally math) problem ratings, especially with problems requiring some knowledge, are not very accurate because how good you are in maths isn't that directly related to how good you are in CP
Problems from unrated contests are generally overrated simply because people don't try as hard in unrated contests as they do in rated contests. So if you want to practice $$$1300$$$-rated problems, you should only choose the ones from rated contests.
The rating might be wrong. The number of solutions is more trustable.
