$$$^\dagger$$$: Began in 2022 at NOI Shanghai, Badge Exchanging has been an activity popular among Chinese CPers. The host school for NOI 2022 decided to print badges containing the avatar of contestants for the contestants, and one can exchange his or her badge with another. The collection of one's badges (of other CPer's avatars) shows the group of CPers that he has met and even made friends offline. It has achieved great success. And since then, it has been a tradition for years.

    Subtasks are good though because if you normally solve n problems with subtasks you you might have a chance to solve n+1 (or n+0.5) problems. And normally I have noticed the first subtasks of problem n is either of the same level or slightly easier than problem n-1.

Score distribution looks really odd. I think it would go something like this, wouldn't it?:

  • Div2: Div2A — Div2B — Div2C — Div2D/Div1A — Div2E/Div1C — Div2F/Div1D
  • Div1: Div2D/Div1A — Div1B — Div2E/Div1C — Div2F/Div1D — Div1E — Div1F

Btw, the badge custom is really cool, I wish I could have done the same when I was younger T.T

As a tester, when my solution has a different output from the example during testing, I suspect the author first.
