Coordbashing = 0?

by UberPiggy, Apr 23, 2025, 10:45 PM

Hi,

I just received my USAJMO score distribution: 000 701 (very cursed I know)

The thing is, I solved #5 (Geometry) by using Cartesian coordinates and tried to show a lot of detail in my calculations. I don't think I mislabeled the pages or anything either. I don't have the scans, but does anyone know why this might be the case? Thank you!

P2 Solution Misgrade?

by Mathandski, Apr 22, 2025, 8:03 PM

Can someone explain to me how this is a zero and not a 5? I wrote the Vieta's equivalent of "two consec zero coefficients", which was worth 5 points

I messed up the numbering and I believe that is the underlying cause of the misgrade but if someone sees any other error, please let me know so I don't wrongly email MAA.

Update: I posted this while flipping out upon seeing a zero on my P2 wanting to find a way to somehow appeal - it genuinely felt like 24JMO4 all over again. Thankfully, this -5 did not game-end my score this year

2024 MATHCOUNTS Nationals alumni from all across the nation have come together to administer the first-ever ELMOCOUNTS Competition, a mock written by the 2024 Nationals alumni given to the 2025 Nationals participants. By providing the next generation of mathletes with free, high quality practice, we're here to boast how strong of an alumni community MATHCOUNTS has, as well as foster interest in the beautiful art that is problem writing!

The tests and their corresponding submissions forms will be released here, on this thread, on Monday, April 21, 2025. The deadline is May 10, 2025. Tests can be administered asynchronously at your home or school, and your answers should be submitted to the corresponding submission form. If you include your AoPS username in your submission, you will be granted access to the private discussion forum on AoPS, where you can discuss the tests even before the deadline.
  • "How do I know these tests are worth my time?"
  • "Who can participate?"
  • "How do I sign up?"
  • "What if I have multiple students?"
  • "What if a problem is ambiguous, incorrect, etc.?"
  • "Will there be solutions?"
  • "Will there be a Countdown Round administered?"
If you have any other questions, feel free to email us at elmocounts2025@gmail.com (or PM me)!

A lot of integer lengths: JMO #6 or USAMO Problem 4

by BarbieRocks, Apr 29, 2010, 1:12 PM

Let $ABC$ be a triangle with $\angle A = 90^{\circ}$. Points $D$ and $E$ lie on sides $AC$ and $AB$, respectively, such that $\angle ABD = \angle DBC$ and $\angle ACE = \angle ECB$. Segments $BD$ and $CE$ meet at $I$. Determine whether or not it is possible for segments $AB$, $AC$, $BI$, $ID$, $CI$, $IE$ to all have integer lengths.
