The instructor really tries to encourage everyone to participate and takes all ideas/comments and either takes or improves on them. I really appreciate how much he shows that he cares about his students and how they learn, as well as taking everything they say seriously.
Program Overview
AlphaStar Computer Science Program aims to train students towards the USA Computing Olympiad (USACO) and similar competitive programming competitions. USACO is the most prestigious pre-college Computer Science competition in the US.
USACO System
The USACO holds periodic web-based contests during the academic year, and in the late Spring conducts the US Open, our “national championship” exam. Contests generally run for three to five continuous hours in length, although for maximum flexibility, you are free to schedule this block of time anywhere within a Friday-to-Monday contest weekend — your timer starts when you log into the contest and download the problems. Contest tasks are presented on the web, and you submit your final solutions through a simple web interface. Participation is free and open to all.
SECURE YOUR CHILD’S SPOT IN THE UPCOMING CLASSES
RegisterContests are offered in four divisions:
- Bronze: for students who have recently learned to program, but who have no training in algorithms beyond basic concepts like sorting and binary search.
- Silver: for students who are beginning to learn fundamental problem-solving techniques (e.g., recursive search, greedy algorithms) and fundamental data structures.
- Gold: where students encounter more standard algorithms of a more complex nature (e.g., shortest paths, dynamic programming) and more advanced data structures.
- Platinum: for advanced students who are well-grounded in algorithmic problem-solving techniques, who wish to challenge themselves with sophisticated and more open-ended problems.
All participants start in the bronze division, and those who score particularly well in a contest will be promoted to the next division. Contestants scoring particularly highly will be automatically promoted to the next division while a contest is running; others will need to wait until results are announced at the end of the contest to see if they meet the (contest-dependent) cutoff for promotion.

Curriculum
Course Types
AlphaStar CS Program has three types of courses: (1) fundamental, (2) booster, and (3) practice test. The following table summarizes the difference between these types.
| Fundamental Courses | Booster Courses | Practice Test Courses | |
|---|---|---|---|
| Objective | Mastery of the programming language or the topics in that USACO level | Improving USACO score in a short time. Recommended after fundamental courses. | Timed practice exams to experience a real exam environment |
| Strategy | Learning the topics of the level and practicing by solving problems that require those topics | Focusing on exam strategies and solving extensive problems in various topics in that level | Exams strategies; how to approach and analyze the problem, find and implement the solution |
| Content | Topics of the level and former USACO or similar problems | Only former USACO or similar problems (problems are different than year-round courses) | Four exams similar to 1 year of USACO. All exams are prepared by AlphaStar. |
| Self-study | Available anytime | Available anytime | Available anytime |
| Live versions offered | During fall / winter / spring / summer | During winter break | During fall |
Fundamental Courses
A fundamental live course can be offered in different paces at different times. Here’s the comparison of the same course offering options:
| Live courses | Fall / Spring Terms | Summer |
|---|---|---|
| Pace | weekly session | daily session |
| Sessions | 16 sessions | 15 sessions |
| Session time | 2 hours | 3 hours |
| Homework (average) | 1 hours per session | rarely |
| Total workload | 32 instruction and practice hours + 16 hours of homework | 45 hours instruction and practice |
| Exams | in-class | in-class |
Note that summer courses require a little bit less time than the year-round ones since students do the practice in class with guidance and they are more focused. On the other hand, students need more time to digest the instruction in year-round courses due to their school work or other distractions.
Levels and Course Flow
The following chart shows levels and summarizes the flow of courses in the AlphaStar CS curriculum:
AlphaStar CS Program has 5 levels some of which have basic and advanced courses as follows (click to the course codes for course details):
- Programming: These courses are for students with very little or no programming background. The aim is to teach the fundamentals of programming and to improve problem-solving skills. Note that the focus is not the language itself but problem-solving in these courses. At this level, there are four different language courses.
- USACO Bronze: These USACO competing courses are for students who have programming and have an Algebra I level math background. This level has 2 fundamental courses, CC25F-1, CC25F-2, and a booster course CC25B.
- USACO Silver: These courses are for students who compete in USACO Silver division. In this level, students are recommended to have AMC 10/12 level math background. This level has 4 fundamental courses, CC31F-1, CC31F-2, CC31F-3 and CC31F-4, and a booster course CC31B. In addition, CC31M: Ada Master Course is a free course for middle school students who are USACO Silver or above division contestants.
- USACO Gold: These courses are for students who compete in the USACO Gold division. In this level, students are recommended to have AIME level math background. This level has 4 fundamental courses, CC41F-1, CC41F-2, CC41F-3 and CC41F-4 and a booster course CC41B.
- USACO Platinum: These courses are for students who compete in the USACO Platinum division. In this level, students are recommended to have a USA(J)MO level math background. This level has 2 fundamental courses, CC51F-1, CC51F-2, and a booster course CC51B. In addition, CC51M: Turing Master Course is free for USACO Platinum division students.
NOTE: In USACO Bronze or above level courses, students can use any of Python, C++, or Java programming languages to solve the problems. Since the solutions of the problems are not language specific but algorithmic, pseudocodes are provided instead of codes. However, when a language specific instruction is necessary, it is provided in Python, C++ and Java.
AlphaStar CS Curriculum vs School CS Curriculum
| School Courses | AlphaStar Courses | Explanation |
|---|---|---|
| Middle / High school Intro to Programming | Programming with Python / C++/ Java | AlphaStar courses focus on in-depth problem solving rather than the language details and object oriented part of the language as in school courses |
| AP CS A | USACO Bronze | USACO Bronze contains some of the topics of AP CS A course but doesn't include object-oriented and software engineering topics. In terms of problem set, USACO Bronze is way more difficult than AP CS A course. |
| College sophomore year Data Structures | USACO Silver | |
| College junior year Algorithms | USACO Gold | |
| Graduate level Advanced Data Structures and Algorithms | USACO Platinum |
