A new generation of studying
MathNerdRabbit103   10
N 43 minutes ago by ObiWanKenoblowin
Based on everything I see from high school students and new Gen Z math fanatics, it seems that what was once considered necessary to succeed, in other terms to gain admission into a great university, is different. Math is the pinnacle of education and a very accurate measurement of one’s capacity to be intelligent and also consistency, that may never change, but with populations increasing and these colleges not, there are new factors that must be considered. Playing an instrument, playing lots of varsity sports, volunteering, and doing leadership activities are all now on the rise, more than it was 20 or so years ago. So, what is the point of all this? The point is that the 4-5 hour regime that parents or students thought or still think is necessary to become the top 1% of mathletes is now inefficient. In a natural 16-hour day, people may allocate more time to more productive activities that will help them succeed. This is why I state my opinion that students should study for 2-3 hours a day, but still stay laser-focused on solving math problems. That way, they could compete with these new kids of different ethnicities who all, because they’re not as smart, are doing other activities to try to look special to universities.

on this list, MATHCOUNTS is clearly the best and it isn't really a contest. I wish it was in high school...

ARML, SMT, HMMT can be fun, but they're not as long

Nothing rivals MathCounts, in my opinion.
The rounds are unique and fun, and provides a great environment for people to make friends and talk about math.

the countdown round makes it very distinct from other competitions and always will be memorable

Hot Take on MathCounts
My personal favorite is usajmo, because the problems require actual thinking and not just spitting out results like LoE and closed form of a linear recurrence (2018 J1 is a counterexample though)
