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!

Hello,
Does anyone know if it’s possible to find the solutions to the 239 Lyceum open math Olympiad somewhere online? Even if it’s in Russian, it would still be okay?

There are no online solutions, as they are published in books called St. Petersburg Mathematical Olympiads for students and they is available only in Russian bookstores (there is such a book for every year, and afaik the book for 2022 is still not out).

I know you said that those books are only available in Russian bookstores, but is it possible to acquire them from outside of Russia? (For example by delivery)

Yes, it is; some bookstores deliver outside Russia (I am also outside Russia and I got delivered some of these books two years ago).

This is the online store of the publisher who produces those books every year.

https://biblio.mccme.ru/

It is in Russian but it can be easily read using Google Translate. E.g., on this search page the first dozen booklets (and books) are the ones mentioned above:

https://biblio.mccme.ru/catalog?fuzzy_everywhere=%D0%97%D0%B0%D0%B4%D0%B0%D1%87%D0%B8%20%D1%81%D0%B0%D0%BD%D0%BA%D1%82-%D0%BF%D0%B5%D1%82%D0%B5%D1%80%D0%B1%D1%83%D1%80%D0%B3%D1%81%D0%BA%D0%BE%D0%B9%20%D0%BE%D0%BB%D0%B8%D0%BC%D0%BF%D0%B8%D0%B0%D0%B4%D1%8B%20%D1%88%D0%BA%D0%BE%D0%BB%D1%8C%D0%BD%D0%B8%D0%BA%D0%BE%D0%B2%20%D0%BF%D0%BE%20%D0%BC%D0%B0%D1%82%D0%B5%D0%BC%D0%B0%D1%82%D0%B8%D0%BA%D0%B5%20

They will ship to the USA. However, there is one major problem - due to sanctions you will not be able to pay for the books. The online payment systems accepted in Russia (MIR, Yandex.Money etc) are not generally available to a regular citizen of the US or Western Europe. If you have someone in Russia or in the US who could pay and make the order you want, great! Otherwise, you'd have to wait until the financial communications are restored.
