The USA Computing Olympiad (USACO) is a computer science competition for secondary school students in the United States. It is organized by the American Mathematics Society (AMS) and the Mathematical Association of America (MAA).

The USACO is a multi-stage competition. The first stage is an online contest that is open to all students in the United States. The top-scoring students from the online contest are invited to participate in the second stage, which is a residential training camp. The top-scoring students from the training camp are invited to participate in the third stage, which is the International Olympiad in Informatics (IOI).
The USACO is a prestigious competition. The top-scoring students in the USACO are often recruited by the top colleges and universities in the United States. The USACO is also a great way for students to learn about computer science and to develop their problem-solving skills.
History of USACO
The USACO was first held in 1994. The competition was created by the AMS and the MAA in response to the growing need for computer science education in the United States. The USACO has grown significantly since its inception. In 1994, only 50 students participated in the online contest. In 2023, over 10,000 students participated in the online contest.
Format of USACO
The USACO is a multi-stage competition. The first stage is an online contest that is open to all students in the United States. The top-scoring students from the online contest are invited to participate in the second stage, which is a residential training camp. The top-scoring students from the training camp are invited to participate in the third stage, which is the International Olympiad in Informatics (IOI).
The online contest consists of four rounds. Each round is three hours long. The rounds are held on consecutive Saturdays in January, February, March, and April. The top-scoring students from the online contest are invited to participate in the training camp.
The training camp is held in June. The training camp is two weeks long. The training camp is held at a university or college in the United States. The training camp is led by a team of experienced computer science educators. The training camp is designed to prepare the students for the IOI.
The IOI is held in July. The IOI is one week long. The IOI is held in a different country each year. The IOI is the most prestigious computer science competition in the world.
Benefits of USACO
There are many benefits to participating in the USACO. The USACO is a great way to learn about computer science and to develop your problem-solving skills. The USACO is also a great way to meet other students who are interested in computer science. The USACO can also help you to get into a top college or university.
There are many things that you can do to prepare for the USACO. The best way to prepare for the USACO is to practice solving computer science problems. You can find practice problems on the USACO website and on other websites. You can also find practice problems in books and magazines.
In addition to practicing solving computer science problems, you can also improve your chances of success in the USACO by taking computer science courses. Computer science courses will teach you the基础知识of computer science and will help you to develop your problem-solving skills.
If you are serious about preparing for the USACO, you should consider attending a training camp. Training camps are led by experienced computer science educators and are designed to help students prepare for the USACO.
