Introduction to Python

Prerequisite:

• 5th grade or above

Times and Dates:

• Tuesdays 7:00-8:30 p.m. PDT

Description:​

This course introduces students to the programming world and teaches absolute beginners step by step. It focuses on basic syntax, data types, flow controls, and basic input/output skills. After this course, students will be able to code in Python using correct flow controls and understand how to work with lists.

Introduction to Java

Prerequisite:

• 8th grade or above

Times and Dates:

• Wednesdays 5:00-6:30 p.m. PDT

Description:

This course teaches Java fundamentals and is tailored for 8th-10th grade beginners by taking out object-oriented concepts and supplying plenty of examples and hands-on practice to master the concepts of data types and flow controls. After this course, students will be proficient at programming with variables of different data types,  flow controls, and Java standard library. Students will be familiar with arrays and methods, but intermediate-level programming and object-oriented principles will be covered in successors.

Introduction to Debate

Prerequisite:

• 6th - 8th grade only

Course Time and Date:

• Sundays 6:30-8:00 p.m. PDT

Description:

In this class, students will learn how to think quickly on their feet, articulate their thoughts confidently, and deliver persuasive speeches. This course introduces students to a competitive

debate environment and focuses on Lincoln-Douglas. In addition to sharpening general argumentative speaking, students will be able to construct a debate case for competitive use and have an introductory understanding of basic Lincoln-Douglas style debate.

CS Fundamentals for ACSL

Prerequisite:

• 5th grade or above

• See the description below

Times and Dates:

• Wednesdays 5:00-6:30 p.m. PDT

Description:

This course is designed to help students participate in ACSL local contests. It covers the twelve topics required, in the order of each local contest. Previous contest problems are used for intensive practice. However, if students are not ready for contests, they can also study this course just for learning fundamental computer knowledge. For those who plan to participate in ACSL contests, Python Programming for ACSL or Java Programming for ACSL should be taken in parallel or finished previously.

Python Programming for ACSL

Prerequisite:

• Introduction to Python

Times and Dates:

• Sundays 10:00-11:30 a.m. PDT

Description:

Designed for students who finished Introduction to Python and wish to improve coding skills through hands-on practice, this course uses many ACSL local contest problems but joining contests is NOT required. It starts by introducing file input/output, then moves to string processing and array operations such as linear searching, finding sums, averages, maximum and minimum, etc. Students will be challenged to work on array sorting as well. Later, method definition and calling chain will be studied and practiced heavily. Lists, stacks, and queues will be explored as well as defining recursive methods to calculate factorials or permute strings.

Java Programming for ACSL

Prerequisite:

• Introduction to Java

Times and Dates:

• Sundays 4:00-5:30 p.m. PDT

Description:

AP Computer Science A 

Prerequisite:​

• 9th Grade or above

• Introduction to Java

• Java Programming for ACSL (highly recommended)

Dates and Times:

• Sundays 10:00-11:30 a.m. PDT

Description:

This course focuses on object-oriented programming in Java and is designed for students who completed Introduction to Java, and preferably, have gained intensive hands-on experience in Java programming for ACSL. We first review arrays and methods to warm up, then transit to the concepts of classes and objects. We will discuss in-depth inheritance and polymorphism, supplement the discussion with many practices, and end with loads of mock exams to prepare for the AP test in May.

USACO & ACSL All-Star

Prerequisites:

• Competed four ACSL local contests and qualified for All-Star previously or

• USACO Bronze contest experience

Time and Date:

• Sundays 10:00-11:30 a.m. PDT

Description:

For students who excelled in ACSL or other coding contests, this course advances them further into algorithmic problem-solving. Students should have been trained on input/output processing, data structures, and fundamental algorithms such as recursion. This program prepares students for the USACO Bronze/Silver contests from December through March. Our mentors will walk students through previous contest problems so they see various algorithms and data structures in actual contest problems.
