HOT TAKE: MIT SHOULD NOT RELEASE THEIR DECISIONS ON PI DAY
by alcumusftwgrind, Mar 15, 2025, 2:11 AM
rant lol
Imagine a poor senior waiting for their MIT decisions just to have their hopes CRUSHED on 3/14 and they can't even celebrate pi day...
and even worse, this year's pi day is special because this year is a very special number...

How to get better at AMC 10
by Dream9, Mar 15, 2025, 1:17 AM
I'm nearly in high school now but only average like 75 on AMC 10 sadly. I want to get better so I'm doing like the first 11 questions of previous AMC 10's almost every day because I also did previous years for AMC 8. Is there any specific way to get better scores and understand more difficult problems past AMC 8? I have almost no trouble with AMC 8 problem given enough time (like 23-24 right with enough time).
AIME score for college apps
by Happyllamaalways, Mar 13, 2025, 1:34 AM
What good colleges do I have a chance of getting into with an 11 on AIME? (Any chances for Princeton)
Also idk if this has weight but I had the highest AIME score in my school.

Tennessee Math Tournament (TMT) Online 2025
by TennesseeMathTournament, Mar 9, 2025, 7:30 PM
Hello everyone! We are excited to announce a new competition, the Tennessee Math Tournament, created by the Tennessee Math Coalition! Anyone can participate in the virtual competition for free.
The testing window is from March 22nd to April 5th, 2025. Virtual competitors may participate in the competition at any time during that window.
The virtual competition consists of three rounds: Individual, Bullet, and Team. The Individual Round is 60 minutes long and consists of 30 questions (AMC 10 level). The Bullet Round is 20 minutes long and consists of 80 questions (Mathcounts Chapter level). The Team Round is 30 minutes long and consists of 16 questions (AIME level). Virtual competitors may compete in teams of four, or choose to not participate in the team round.

OTIS Mock AIME 2025 airs Dec 19th
by v_Enhance, Dec 6, 2024, 7:08 PM
Satisfactory. Keep cooking.

Problems are posted at https://web.evanchen.cc/mockaime.html#current now!
Like last year, we're running the OTIS Mock AIME 2025 again, except this time there will actually be both a I and a II because we had enough problems to pull it off. However, the two versions will feel quite different from each other:
Details are written out at https://web.evanchen.cc/mockaime.html, but to highlight important info:

Like last year, we're running the OTIS Mock AIME 2025 again, except this time there will actually be both a I and a II because we had enough problems to pull it off. However, the two versions will feel quite different from each other:
- The OTIS Mock AIME I is going to be tough. It will definitely be harder than the actual AIME, by perhaps 2 to 4 problems. But more tangibly, it will also have significant artistic license. Problems will freely assume IMO-style background throughout the test, and intentionally stretch the boundary of what constitutes an “AIME problem”.
- The OTIS Mock AIME II is meant to be more practically useful. It will adhere more closely to the difficulty and style of the real AIME. There will inevitably still be some more IMO-flavored problems, but they’ll appear later in the ordering.
Details are written out at https://web.evanchen.cc/mockaime.html, but to highlight important info:
- Free, obviously. Anyone can participate.
- Both tests will release sometime Dec 19th. You can do either/both.
- If you'd like to submit for scoring, you should do so by January 20th at 23:59 Pacific time (same deadline for both). Please hold off on public spoilers before then.
- Solutions, statistics, and maybe some high scores will be published shortly after that.

Let
be an integer. Rowan and Colin play a game on an
grid of squares, where each square is colored either red or blue. Rowan is allowed to permute the rows of the grid and Colin is allowed to permute the columns. A grid coloring is orderly if:
, how many orderly colorings are there?
Proposed by Alec Sun


- no matter how Rowan permutes the rows of the coloring, Colin can then permute the columns to restore the original grid coloring; and
- no matter how Colin permutes the columns of the coloring, Rowan can then permute the rows to restore the original grid coloring.
