Bogus Proof Marathon

Hi!
I'd like to introduce the Bogus Proof Marathon.
In this marathon, simply post a bogus proof that is middle-school level and the next person will find the error. You don't have to post the real solution :P
Use classic Marathon format:

300 MAP Goal??
Antoinette14 53
Hey, so as a 6th grader, my big goal for MAP this spring is to get a 300 (ambitious, i know). I'm currently at a 285 (288 last year though). I'm already taking a intro to counting and probability course (One of my weak points), but is there anything else you recommend I focus on to get a 300?

Deciding between Ross and HCSSiM
akliu 10
Hey! I got accepted into Ross Indiana, and I think I'll probably also get accepted into HCSSiM. I've been looking between the two camps, and I'm trying to decide which one to go to -- both seem like really fun options.
Instead of trying to explain my personal preferences and thought processes, I thought it might be a good idea to ask the community for their personal opinions on these camps. What are some things that you like or dislike about both camps? (Whether it be through personal experience or by word-of-mouth, but please specify if it's just something you've heard)
This will probably help me be more informed on making a final decision, so I'd appreciate any advice. Thanks in advance!

If so, I will put tentative answers on this thread.
By the way, does anyone know the answer to Geometry Problem 5? I was wondering if I got that one right
Also, if you put answers, please put it in a hide tag

Did anyone archive the AMC statistics from the old MAA website
Kevedu 11
Hi everyone, this is the first time I'm writing something here(in comparison to the past 10 years of just looking at cool posts).
I'm looking for the amc statistics (all of the data) that was originally archived in this link
https://amc-reg.maa.org/reports/generalreports.aspx
It had some important data sets like: number of perfect scorers each year, the number of DHRs, item difficulty, difficulty by grade and gender, etc
If anyone archived the statistical data, pleeeeeaaase let me know!
thanks.

100 ones are written in a circle. Petya and Vasya take turns making 
moves each. In each move, Petya chooses 9 consecutive numbers and decreases each by 2. Vasya chooses 10 consecutive numbers and increases each by 1. They alternate turns, starting with Petya. Prove that Vasya can act in such a way that after each of his moves, there are always at least five positive numbers, regardless of how Petya plays.

Introducing myself at AoPS, and what's your magic wand?
asuth_asuth 906
Hi!
I'm Andrew Sutherland. I'm the new Chief Product Officer at AoPS. As you may have read, Richard is retiring and Ben Kornell and I are working together to lead the company now. I'm leading all the software and digital stuff at AoPS. I just wanted to say hello and introduce myself! I'm really excited to be part of the special community that is AoPS.
Previously, I founded Quizlet as a 15-year-old high school student. I did Course 6 at MIT and then left to lead Quizlet full-time for a total of 14 years. I took a few years off and now I'm doing AoPS! I wrote more about all that on my blog: https://asuth.com/im-joining-aops
I have a question for all of you. If you could wave a magic wand, and change anything about AoPS, what would it be? All suggestions welcome! Thank you.

k repeated deletion of EGMO threads in HSO
InterLoop 3
I hope posting this in Site Support is fine? I'm not sure whether an HSO admin is doing this but-
The EGMO 2025 problem 1 and problem 2 were originally posted by me on the day of the contest and found deleted (not by me) yesterday. Someone else noticed this and posted the problems again, but these threads were deleted once more.
