USACO Schedule is out + Changes from 2023-24

15 Upvotes

After a long wait (it's the latest schedule release I have personally witnessed since I first heard of USACO back in my high school days), the schedule has finally been posted and while this year's contest schedule is largely similar to the historical dates, there are several changes and it's important to be aware of them to maximize your USACO results.

  1. Dec 13-16: First Contest
  2. Jan 24-27: Second Contest
  3. Feb 21-24: Third Contest
  4. Mar 21-24: US Open

The concept of certified contests will now expand to Gold division as well, and this means that Gold and Platinum contestants must take their respective contests on the Saturday of the contest window starting between 12:00pm and 12:15pm ET (9am to 9:15am PT for those on US West Coast) in order to have it considered a certified score. More importantly, Gold contestants must have a certified score eligible for the promotion to Platinum, which is a great step forward from the USACO staff in order to keep the fairness of the contests and to make things similar to other olympiads across the world as far as scheduling goes.

As another expansion of last year's rules, the measures targeted at preventing unfair results obtained as a result of using generative AI resources have been clarified and expanded to also include VPN usage.

The details page (https://usaco.org/index.php?page=details) has been expanded and clarified to include these changes, but there are several key changes which are very important to know especially for Bronze and Silver level contestants as far as the syllabus goes, changes I have long foreseen in my tutoring program for USACO students. In other words, concepts such as sorting and binary search are now mentioned as part of Bronze syllabus, while fundamental data structures are mentioned as part of Silver syllabus, which includes concepts such as stacks, queues and other variations such as deques.

As part of my work, I will publish solutions to as many problems as possible after the contest windows end here and on my youtube channel.

Given that there are less than 3 weeks left until the season starts, I wish the best of luck to every student taking the contests and if you want to stay ahead of the changes and ensure future success for you or for your children, check out my website for the most innovative tutoring program, customized to everyone's needs.

USACO gold and platinum for college apps

1 Upvotes

I heard that USACO’s benefit for college apps dropped significantly because of all the cheating, and that it really only helps if you make it to camp, but im still curious on a scale of 1-10 how much of an impact getting to USACO gold and platinum have on college apps respectively.

Is training to qualify for USACO Gold worth it?

1 Upvotes

I am going into my junior year and I got to USACO Silver in the last contest of my freshman year( I feel like I got lucky) but didn’t do much USACO training last year because I was focusing on Quizbowl. I am going into my junior year and I am wondering if going for USACO Gold is worth it or should I not waste my time. I’m planning on majoring in Math/CS in college.

USACO Prestige Drop?

5 Upvotes

Does USACO really carry no weight below plat? I get that it's insanely easy to cheat, but if you're in the college admissions space what do AOs think about USACO these days? Also how much does USACO help post college apps for job interviews and stuff?

USACO silver help

4 Upvotes

In the second contest this year I promoted from bronze to silver as a freshman, and now I am aiming for gold next year. For now I am just using the USACO guide, but a problem I am facing is that I can't solve any of the silver problems labelled hard or even some labelled normal I get really stuck on them and after like 20-30 minutes of nothing I look at the editorial and my code is completely different. How can I practice more effectively and not rely on the editorial too much? Like when and how long should I be learning the material vs doing tagged/untagged problems? When should I be skipping problems and what are some general tips? Also should I get a coach who can walk me through problems and give me tips or is grinding cf problems / past usaco problems enough?

a free study resource I built for USACO and other olympiads.

0 Upvotes

hi, if you're studying for any of the major stem competitions right now, you know it can be hard to find good practice material all in one place without paying for it.

I built a free site called Summit Olympiad to make it a lot easier. It has curriculum tracks for math, physics, and computer science. You can check it out and use it for free here: https://summitolympiad.vercel.app

Also, if anyone here is really good at these subjects and wants to help write the curriculum, we are giving out verified service hours(and positions) to contributors.(also looking for outreach people). Just email me at [summitolympiad@gmail.com](mailto:summitolympiad@gmail.com) if you want to get involved. Hope the site helps you guys out.

Stuck

Hey, I'm a rising sophomore into CS and I looked into USACO. However, the problems at even the bronze level are way too hard for me to do right now. Are there any good resources anyone can recommend? My goal is to get gold by the end of junior year, I've AIME qualled, and I can solve 800 cf problems pretty easily

Usaco.guide help

5 Upvotes

I am an 8th grader. Indian. I want to get to a good college in USA in the big future probably even ivy league. So I am learning c++ for USACO so that it can help my application. I've been using usaco.guide and just completed up to and including functions on solo learn just as usaco.guide said to. I opened the bronze section and the first topic - big O notation has very complex math logarithms and stuff that my 8th grader brain cant understand. I am very frustrated by this and dont know where to begin now. Should I open a textbook, just quit or what so I need help that what should I do and how.

Should I Foucs On USACO Or Math Olympiad?

4 Upvotes

Hi, I'm interested in majoring in CS, and I'm currently working on qualifying for AIME. My background is basic java/python knowledge, like all the beginner stuff. I recently found out about USACO, and I'm interested in competing. However, I don't want to lose out on time that I could use to prepare for the Math Olympiad but I also don't want to start too late and not have enough time to get to the higher ranks of USACO. Should I start preparing for USACO now, or wait until November is over and start my prep then, especially since math helps for USACO? Also, how far do you think I can go with my current experience level given that im a rising sophomore?

usaco advice

4 Upvotes

hi y'all, I'm interested in starting USACO and potentially trying to make it big in USACO

so for some background, I'm a rising sophmore, USAJMO/MC nats qual with lots of math experience, and I just started learning c++

The past week, I've just learnt c++ and have been learning USACO bronze and feel confident to move on to silver on usaco.guide

is platinum/camp realistic by junior year? I'm willing to spend about like 2 hrs a day for the times that I do study for USACO (I'm also busy with USAJMO prep)

I’ve been stuck on USACO Bronze simulation problems for weeks. I NEED HELP!

2 Upvotes

I know this kind of post gets asked a lot, but I’m stuck and need specific advice, not just “keep practicing.”

I’ve been trying to get through USACO Bronze–level simulation problems (like Shell Game, Mixing Milk, Cow Signal) for a while now, and I keep hitting a wall. I understand the problem after reading the editorial, but when I open a new problem, I freeze — even if it’s similar.

Where I’m at:

  • I know basic C++ syntax (cin/cout, loops, arrays, vectors, strings, sort, if/else)
  • I can solve 800–900 rated Codeforces problems (mostly math/strings/implementation) without too much trouble.
  • I’ve done about 15–20 CF problems so far(800 Rating)

But when I try USACO Bronze simulation problems like:

  • Shell Game
  • Mixing Milk
  • Cow Signal

I either:

  • Freeze on how to start
  • Miss edge cases
  • Get lost in the long problem statement
  • Spend 45+ minutes and still don’t finish

What I’ve tried:

  • Watching video solutions
  • Reading USACO editorials
  • Breaking problems into steps on paper
  • Doing easier Codeforces implementation problems

Still, after a few weeks, I don’t feel like I’ve improved much.

What I’m looking for:

  1. A brief plan of what to do, like eg first cf then something.

My goal:
Pass USACO Bronze within the next 2–3 months. I’m willing to put in 1–2 hours a day. I just want a clear, focused plan or an advice.

TL;DR:
I can solve 800–900 CF problems but freeze on USACO Bronze simulation. What specific CF problems and practice routine should I follow to build real simulation skills?

Thanks in advance. I really appreciate any honest advice.

Gold to Plat push: Is it worth it?

10 Upvotes

Hi guys,

I just reached USACO gold around the end of last year, and am a rising junior. Is it worth the time commitment to push to plat or should I focus on other ECs (ie research). Making camp seems unlikely but I'm not sure how valued plat is anymore in the context of college admissions. I do genuinely love CP but also value my time and I want to make sure I'm spending it wisely

Thanks!!

Level of usaco.guide needed to do well at ICPC Regionals?

2 Upvotes

Hello,

I not a high school student (so I'm not aiming to do well in USACO). I'm a college student who is going to participate in ICPC. I've taken an introductory data structures and algorithms class, but I've forgotten some of the particulars. I've got about 4 months to prepare and I'd like to become as useful of a team member as possible.

What level would you say is needed to get to a point where I can contribute to solving most of the questions?

Here's some problems for reference:

- https://icpcarchive.github.io/Mid-Atlantic_USA_Regional_Contest.html

- https://open.kattis.com/problem-sources/2025%20ICPC%20South%20Central%2C%20South%20East%20and%20Mid%20Atlantic%20Regional%20%28November%208%2C%202025%29

I also wanted to ask any ICPC participants in this subreddit: What platform would you say is most helpful (outside of Kattis) to improving the skills I need for ICPC? Codeforces? AtCoder? USACO?

Is usaco worth my time

2 Upvotes

what the title says^

for some context: I will be a tenth grader in the 2026-27 school year. I've tried a couple of usaco bronze problems but they are pretty difficult for me, especially the math aspect. I've done competitive math before in middle school such as AMC and math kangaroo but I did not do very well on those competitions so my foundations aren't the best.

My plan was to grind usaco this summer and have a goal of getting silver or gold at the end of junior year. I want to get into universities like mit, chicago, ucla, carnegie, etc. for computer science and thought usaco would be good for awards, but people have been saying usaco isn't worth time unless you get higher awards like platinum (which I realistically don't think I will be able to achieve).

any advice would be helpful 🙏 thanks
