9 RSM or AoPS?
BlazingSun1200   69
N 14 minutes ago by Yihangzh
I'm doing RSM right now, but I want to switch over to AoPS. I'm just curious to know, which do you prefer? (If you have no experience with both, please don't vote!)

If you want, please drop some advice on the Intermediate Algebra class, because that's the one I'm hoping to take!

Columbia Science Honors Program Entrance Exam
am07   2
N an hour ago by SmartGroot
Source: SHP
Hello everyone, I am planning on applying to the Columbia Science Honor Program (SHP) in a year or two and I am trying to see what material is covered on the entrance exam so I can start revising soon. I don't have much of a concern with most of the science topics but I am not sure what kind of math will potentially appear on the test. Will it be traditional school math, SAT math, or even competition math at the AMC or AIME+ level? For anyone who has taken the exam before or has gotten into the program, can someone please elaborate? Thank you.

How to get good at comp math
fossasor   23
N an hour ago by fossasor
I'm a rising ninth grader who wasn't in the school math league this year, and basically put aside comp math for a year. Unfortunately, that means that now that I'm in high school and having the epiphany about how important comp math actually is, and how much it would help my chances of getting involved in other math-related programs. In addition, I do enjoy math in general, and suspect that things like the AMCs are probably going to be some of the best practice I can get. What this all means is that I'm trying to go from mediocre to orz, 2 years after I probably should have started if I wanted to be any good.

So my question is: how do I get good at comp math?

This year, my scores on AMC 10 (and these are the highest I've ever gotten) were a 73.5 and an 82.5 (AMC 8 was 21/25, but that doesn't matter much). This is not good enough to qualify for AIME, and I probably need to raise my performance on each by at least 10 points. I've been decently good in the past at Number Theory, but I need to work on Geo and Combinatorics, and I'm trying to find the best resources to do that. My biggest flaw is probably not knowing many algorithms like Stars and Bars, and the path is clear here (learn them) but I'm still not sure which ones I need to know.

I'm aware that some of this advice is going to be something like "Practice 5 hours a day and start hardgrinding" or something along those lines. Unfortunately, I have other extracurriculars I need to balance, and for me, time is a limiting resource. My parents are somewhat frowning upon me doing a lot of comp math, which limits my time as well. I have neither the time nor motivation to do more than an hour a day, and in practice, I don't think I can be doing that consistently. As such, I would need to make that time count.

I know this is a very general question, and that aops is chock-full of detailed advice for math competitions. However, I'd appreciate it if anyone here could help me out, or show me the best resources I should use to get started. What mocks are any good, or what textbooks should I use? Where do I get the best practice with the shortest time? Is there some place I can find a list of useful formulas that have appeared in math comps before?

All advice is welcome!

Contest resources guide with levelling system (from AMC8 to USAMO/IMO)
Konigsberg   9
N Feb 19, 2025 by Andyluo
Source: own
Hi,

As part of my work with my country’s national olympiad system, I am developing a public resource guide on math contests. This guide covers every stage of contest participation, from complete beginners to those aiming for the highest levels of the USAMO and IMO.

I would be grateful for any feedback; if you have additional resource suggestions, please share them in this thread or by AoPS DM to foster discussion. I also particularly welcome comments as to whether a resource may be under/over-classified in the guide.

The following is the leveling system used, aligned with the corresponding tiers of the US contest framework. Note that the guide indicates the suggested practice contest or textbook for someone aspiring to reach the corresponding level, not someone currently at that level.

J: Strong middle-school student with little math exposure outside the curriculum
1A: Strong high-school student with little math exposure outside the curriculum, or Middle-school student scoring 20-35 at Mathcounts chapter
1B: AMC8* Honor Roll, AMC10 score of ~60-70
2A: AMC8 Distinguished HR, AMC10 score of ~80-90
2B: AIME qualifier (through either AMC10/12), AMC10 Honor Roll
3A: AMC10 Distinguished HR, AMC12 HR
3B: AMC12 Distinguished HR, USAJMO/USAMO Qualifier
4A: USAJMO Honorable Mention, USAMO ~50th percentile
4B: USAJMO Honors, USAMO Bronze, Red/Green MOP Cutoff
5A: USAJMO Top Honors, USAMO Silver, Blue MOP/TST Group Cutoff
5B: USAMO Gold, USAMO RMM/IMO team selection

I think you kind of overestimate how hard the books are--maybe move them up down 1-2 spots? I'm not that familiar with a lot of the books but in my opinion, intermediate c&p is approachable for any AIME qualifier/AMC 10 honor roll and OTIS excerpts are approachable for AMC 10 DHR
there is a great variety of resources though :)

Interesting, this might be a generational thing. Back in my day (I finished high school in the mid-2010s), there were far fewer resources so we typically aimed for near-complete mastery of the texts we came across! But I understand that current students prefer exposure to a wider range of topics, early on.

I also updated the level description to be that the level corresponds to a student aiming to reach that level.

1. In your PDF file, AIME is listed on Level 3A while here it is on Level 2B, is 3A in your PDF guide refer to the difficulties level?
2. Is Level 3B just slightly harder than 3A that why both still stay at 3 instead of 4?
3. For someone aim to reach the top 10% in AIME, which textbook level should they focus on?
4. Is Level 4 and above mainly proof based questions?
