ACSL/USACO Students Circle

Overview

 ACSL (American Computer Science League) - 45+ years World level CS exams and contests.

USACO (United States of America Computing Olympia is one of the most challenging pre-college Computer Science Exams/Contests.

They both hold about four web-based contests/exams during the academic year.

 ACSL

Exams are designed to increase students' competency in CS with computational thinking from Elementary to Grade 12. Their

 USACO

Exams are designed to challenge even the very best students, and it can take a good deal of hard work and passion in problem-solvings with programming to excel at them.

Students take the exams online on their own. The majority of our Algorithms in C/C++ Level II students with high proficiency demonstrated remarkable performance.

This is NOT a class, but a discussion group. In order to be productive, students MUST possess passion in algorithmic programming, and be self-motivated (e.g. not being told by parents, not rushing thru to get problems complete without demanding themselves for the best result, etc. ) Thus, inquiry must be received from the students.

Do note: if you do not like error-checking, trouble-shooting or being inquisitive "what-ifs", or do not like to revise your work as sugggested by the instructor, etc., this is not for you.

Prerequisites:

• Develop a good knowledge of data structures like lists, trees, and graphs. Complete Algorithms in C/C++ - II.
• MUST love problem solving and open discussion;
• MUST LOVE PROGRAMMING and algorithmic thinking;
• MUST be willing to work through algorithmic problems on his/her own time, and collaboratively in the meetings!

If the student has met the prerequisites, please have the student  emailing us to acquire for the meeting link.

What if my child has never started with Algorithms in C/C++?

Please go here to view details.

This is a Students-Driven group which meet once a week to work on USACO problems collaboratively. This is NOT a class.

Due to limited resources, all discussions have been limited to our internal PRIVATE Discord Server. Students will continue to gain the advantage of open discussion of any algorithmic discussion online at their own convenience. They can have any extended interesting discussion, sharing and communication regarding algorithmic programming topics.

There is no shortcut to this. BEST PRACTICE...

• Basic rule of thumb - to understand and analyze, NOT by rote memorization and syntax recall.
• There is NO substitue of practices. Go thru their past exams. Be inquisitive. Try things out!
• The more practice you get, and the better programmer you become.
• One must love problem-solving with programming. That requires one's intrinsic love of being inquisitive.
• One must love debugging, trouble-shooting and often being inquisitive, understanding and shooting for the best result.
• When it comes to learning algorithms - put yourself in analysis mode and implement them.
• Don't settle with basic given test cases. Think about exceptions - normal to worst cases. List test cases and test your code.
• Work on the problems sets in the USACO.org site. Understanding the problem, practice, submitting and re-submitting solutions until you get the best result.

2021-Fall to 2022-Spring: Group leader: Arjun Subramanian

Arjun attended Storming Robots' CS Track program since his 5th grade, and started to lead SR's USACO Students Circle since his 8th grade. He possesses a deep passion for problem-solving with programming. He has advanced to the USACO Gold division at 8th grade. He has broadened his CS knowledge by self-studying thru Coursera in various topics, including Princeton’s Algorithms (Part 1 and 2), Managing Big Data with MySQL, and Algorithms Theory and Machines. He has also taught Python since the 2021 Summer and continues throughout the school year. Some of his other interests include skiing, squash, and play chess. Here is his GitHub.

2021-Spring: Group leader- Brian Gan.

Brian, a USACO Gold level achiever at 11th grade, has been at SR as both computer science and robotics student since he was in early middle school. He has a deep passion in problem solvings. Brian took the initiative to start this group and hope to further increase the interest and strength in algorithmic programming. He was admitted to Purdue University- Class of 2025 as CE major.
