I know this post has been made before, but I personally can't find it. I qualified for mathcounts through wildcard in PA, and I can't figure out how to do those last handful of states sprint problems that seem to be one trick ponies(2024 P28 and P29 are examples) They seem very prevalent recently. Does anyone have advice on how to figure out problems like these in the moment?

Let $S$ be a set of integers with the following properties:
[list]
[*] $\{ 1, 2, \dots, 2025 \} \subseteq S$.
[*] If $a, b \in S$ and $\gcd(a, b) = 1$, then $ab \in S$.
[*] If for some $s \in S$, $s + 1$ is composite, then all positive divisors of $s + 1$ are in $S$.
[/list]
Prove that $S$ contains all positive integers.

What got you guys into math? I'm asking because I got ~71 on the AMC 12B and 94.5 on 10A last year. This year, my dad expects me to get a 130 on 12B and 10 on AIME, but I have sort of lost motivation, and I know these goals will be impossible to achieve without said motivation.

school math was way too boring, so when i first really got into math contests in 7th, i was very excited by the fact that instead of just practicing the mechanics, the mechanics were just tools you used to solve puzzles.
Retrospectively, I realize when I was young i'd create these problems for myself based on the things i noticed around me. Two examples of this lived in my old kitchen: this tiled thing that lived behind the stovetop, and a digital clock. On the former I would imagine different polyominoes and play around with them in my mind. With the later, I noticed the sum-of-digits mod 9 thing (which of course i wasn't aware of at the time), and would try to come up with patterns amongst the numbers. I bet my parents were probably so confused why I'd be staring at the clock for 15 minutes and forgot to eat :) So it was (still is) so cool to realize that all the random crazy ideas i have can be used to solve problems.
It certainly doesn't hurt college apps, either. But I also think the specific score itself doesn't really matter as much. (Ex: You're not gonna get rejected from someplace if you have a 220 index instead of a 221). (I don't have either welp--)

1. I enjoy doing math (a lot). I started when I was 3-4 years old and never got tired of it.
2. I’m actually cooked for college apps if I don’t clutch up on the AMC/AIME

(Like seriously tho, it’s 2025. Literally EVERYTHING is hyper-competitive. Like, if I failed the AMC then my gyatt doesn’t even stand a chance to get into a good college. Unfortunately, nowadays there are just too many smart people out there, which means more opps to battle tryna get into college.)

I started Beast Academy and later AoPS in 5th grade because my parents wanted me to be challenged more, but I made the decision to start comp math in 7th grade. I won't lie that college apps aren't a motivator, but it's more importantly that I enjoy problem solving and meeting other people who do.
