There is still time to train for the November 6th and November 12th AMC 10A/12A and AMC 10B/12B, respectively! Enroll in our weekend seminars to be held on November 2nd and 3rd (listed below) and you will learn problem strategies, test taking techniques, and be able to take a full practice test! Note that the “B” seminars will have different material from the “A” seminars which were held in October.

For those who want to take a free practice test before the AMC 10/12 competitions, you can simulate a real competition experience by following this link. As you assess your performance on these exams, be sure to gather data!

[list][*]Which problems did you get right?
[list][*]Was the topic a strength (e.g. number theory, geometry, counting/probability, algebra)?
[*]How did you prepare?
[*]What was your confidence level?[/list]
[*]Which problems did you get wrong?

Stress during competitions
happypi31415   2
N 6 minutes ago by GallopingUnicorn45
I noticed that during big tests, I think the percieved time pressure and high stakes mimic countdown rounds in mathcounts, so my brain defaults to a countdown round mentality. while this is fine in contests like mathcounts, where the first ~10 questions on sprint rounds are essentially countdown round questions and it gives me a chance to get into the flow of things, on tests like the AMC 10 this can really hurt -- notable examples of this include #2 on this year's 10A which was a system of equations. when i saw that the system didn't neatly add to get the desired answer, i panicked and spent ~3 minutes trying to find a neat way before ending up skipping it and coming back to it after problem 17. this is a really big time waste, and i probably spent ~5 minutes total working on it. however, if the problem was the only thing on the paper, I think i definitely would have solved it in <2.

(other examples could be #7 on this years 10B, which was on $7^{2024}+7^{2025}+7^{2026} \pmod{19}$. this one i panicked over because i misread $19$ as $17$ on this problem and didn't get an answer choice, so i again ended up skipping this one and spending way too long on it)

while these aren't necessarily huge time wastes, the psychological affect of skipping an early problem can really impair ur mental state while doing later problems as you won't be as confident

how do i counteract this, and get into the 'flow state' immediately? on mocks this doesn't happen, only in real contests.

also on the AIME this isn't a problem

generic whiteboard problem

N 19 minutes ago by happypi31415
Source: 2024 AMC10B p16
Jerry likes to play with numbers. One day, he wrote all the integers from $1$ to $2024$ on the whiteboard. Then he repeatedly chose four numbers on the whiteboard, erased them, and replaced them with either their sum or their product. (For example, Jerry's first step might have been to erase $1, 2, 3$, and $5$, and then write either $11$, their sum, or $30$, their product, on the whiteboard.) After repeatedly performing this operation, Jerry noticed that all the remaining numbers on the board were odd. What is the maximum possible number of integers on the board at that time?

\textbf{(A) }1010 \qquad
\textbf{(B) }1011 \qquad
\textbf{(C) }1012 \qquad
\textbf{(D) }1013 \qquad
\textbf{(E) }1014 \qquad

Possibility of USAMO?
MathXplorer10   4
N Yesterday at 8:05 AM by MathXplorer10
Hi guys!


I got a 118.5 on the 12B test this year. I am wondering if it is possible to make USAMO (what do you think the cutoffs would be this year?)

For some background, I got 121.5/127.5 on the 10s last year, and got a 7 on AIME with no extra prep. Is it possible to go from a 7 to a 10 (or whatever I need to get on AIME)?

Thank you!

Yeah true... you think the cutoffs would be 230s/240s?

Tbf, you will need a *12* on the AIME to be safe which is going to be difficult( cutoff is likely to be in the late 220's, so 231 should be fine). For context, that is going to be pretty hard- I got a 141 on the amc 12, and mock around 9 on AopS mock AIME, and am trying to prepare to get a 10 on the real deal. That means you will have to solve 13 problems( sillies for the loss) which is INSANLY hard- the AIME is like the last 15 on the amc 12, but buffed up even more. You can always try next year. I know I sound cyclical, but its the truth- 12 is going to be objectively hard to get to

Oh ok thank you for the honest feedback! Yeah a 12 would be tough!

Congrats on 141 :)
