[list][*]Over 60 summer classes are starting at the Virtual Campus on July 7th - check out the math and language arts options for middle through high school levels.
[*]At AoPS Online, we have accelerated sections where you can complete a course in half the time by meeting twice/week instead of once/week, starting on July 8th:
[list][*]MATHCOUNTS/AMC 8 Basics
[*]MATHCOUNTS/AMC 8 Advanced
[*]AMC Problem Series[/list]
[*]Plus, AoPS Online has a special seminar July 14 - 17 that is outside the standard fare: Paradoxes and Infinity
[*]We are expanding our in-person AoPS Academy locations - are you looking for a strong community of problem solvers, exemplary instruction, and math and language arts options? Look to see if we have a location near you and enroll in summer camps or academic year classes today! New locations include campuses in California, Georgia, New York, Illinois, and Oregon and more coming soon![/list]

Qualifying for USAJMO
Youlose.com   7
N 38 minutes ago by martianrunner
So basically I'm going to be in 9th grade in the fall, I'm averaging 102-108 on practice AMC 10s and averaging 7-8 on AIMEs so I'm wondering what I still need to do to bump AMC 10 like 25 points and AIME like 2 points. I've done all the intros, about to start intermediates, and also going to do some Awesome math books. I'm trying to find some good books for geometry(my weakest subject) as well as other books that are in between AoPS Intros and Intermediates as well as some that are more advanced than the intermediates. Specifically, I'd like an advanced NT book(my strongest subject), a C&P/Combinatorics book that's between Intro and intermediate. Also generally AIME books as well.

an hour ago
Hey everyone! I'm excited to share some big news for anyone preparing for math contests like the AMC, AIME, or USAMO/USAJMO.

I've launched Mathema, a completely FREE online platform designed to help you tackle challenging problems. Mathema offers intelligent hints to guide you without giving away the answer, fostering true understanding. Plus, it can grade your proofs on a scale of 0-7, providing instant feedback to refine your argumentation skills.

You can learn more and get started right away at: Mathema

I've also made a more detailed announcement in the Peer to Peer Programs Forum here: https://artofproblemsolving.com/community/c1967976h3608853_big_news_for_aspiring_math_olympians_introducing_mathema

Sequences of Subsets
tenniskidperson3   140
N 3 hours ago by eg4334
Source: 2016 USAMO 1/USAJMO 3
Let $X_1, X_2, \ldots, X_{100}$ be a sequence of mutually distinct nonempty subsets of a set $S$. Any two sets $X_i$ and $X_{i+1}$ are disjoint and their union is not the whole set $S$, that is, $X_i\cap X_{i+1}=\emptyset$ and $X_i\cup X_{i+1}\neq S$, for all $i\in\{1, \ldots, 99\}$. Find the smallest possible number of elements in $S$.
