for 25 hoursThe ACSL is the longest running computer science contest in the United States since 1978. Since 2020 the contest is open to people online worldwide through KTBYTE. This club will allow students to review material, receive live instructions practicing historical contests, and participate together as a team in KTBYTE.

**Clubs are run by qualified, award-winning KTBYTE Teaching Assistants.**

Age 15-18, Grades 9-12

These are examples of projects that students create as they grow their skills in [ACSL ADVANCED]

Computer Number Systems

This class focused on computer number systems.

Recursive Functions

This class focused on recursive functions.

Contest 1 - What Does This Program Do?

Today we learned about analyzing and solving problems involving pseudo code!

Review for Contest 1

Today, we reviewed for the shorts portion of Contest 1 by completing miscellaneous problems that have shown up on past contests.

Contest 1 Programming

Today we practiced solving programming problems from past years' first contests.

Contest 1 Programming

Today we continued practicing solving programming problems from past years' first contests.

Contest 2 - Prefix, Infix, Postfix Notation

Today we learned how to solve problems involving prefix, infix, and postfix notation. This type of question appears in problems 1-2 of contest 2.

Contest 2 - Bit-String Flicking

Today we learned about Bit-String Flicking, a concept that involves some boolean algebra along with other logical operators with 0s and 1s. The notation takes some getting used to, but once you understand it, you'll be able to solve some very interesting ACSL problems!

Contest 2 - LISP

Today we learned about LISP, one of the first functional languages invented in 1958. It is infamous for having lots of parentheses, so much so that we often joke that LISP stands for “Lots of Irritating Silly Parentheses.”

Contest 2 - More LISP

Today we learned about LISP, one of the first functional languages invented in 1958. It is infamous for having lots of parentheses, so much so that we often joke that LISP stands for “Lots of Irritating Silly Parentheses.”

Contest 2 Programming

Today we practiced solving programming problems from past years' second contests.

Review for Contest 2 (Session 1)

Today, we reviewed for the shorts portion of Contest 2 by completing miscellaneous problems that have shown up on past contests.

Review for Contest 2 (Session 2)

Today, we continued reviewing for the shorts portion of Contest 2 by completing miscellaneous problems that have shown up on past contests.

Contest 3 - Boolean Algebra

We learned about solving problems involving the first Contest 3 topic, Boolean algebra.

Contest 3 - Data Structures

We learned about solving problems involving the second Contest 3 topic, Data structures. These include queues, stacks, and binary search trees.

Contest 3 - FSAs and Regular Expressions

Today, we talked about Regular Expressions, which are a way we can represent patterns of Strings. Finite State Automatons (FSAs) model these as a sequence of states and transitions.

Contest 3 Programming

Today we practiced solving programming problems from past years' third contests.

Review for Contest 3 (Session 1)

Today, we reviewed for the shorts portion of Contest 3 by completing miscellaneous problems that have shown up on past contests.

Review for Contest 3 (Session 2)

Today, we continued reviewing for the shorts portion of Contest 3 by completing miscellaneous problems that have shown up on past contests.

Contest 4 - Graph Theory

We explored Graph Theory, which involves a mathematical concept called matrix multiplication.

Contest 4 - Digital Electronics

Today, we learned about solving problems involving the second Contest 4 topic, Digital Electronics. This topic is an extension of Boolean Algebra. In fact, it’s simply a visual representation of Boolean algebra expressions using circuits, so bring all your Contest 3 Boolean algebra knowledge to the lesson!

Contest 4 - Assembly

Today we learned about analyzing and solving problems involving ACSL's Assembly programming language.

Review for Contest 4

Today, we reviewed for the shorts portion of Contest 4 by completing miscellaneous problems that have shown up on past contests.

ACSL Senior/Intermediate Finals Review Session 1

Today, we reviewed for the shorts portion of ACSL Senior and Intermediate Finals by completing miscellaneous problems that have shown up on past contests. We also discussed some trickier application of previous concepts already taught.

ACSL Senior/Intermediate Finals Review Session 2

Today, we reviewed for the shorts portion of ACSL Senior and Intermediate Finals by completing miscellaneous problems that have shown up on past contests. We also discussed some trickier application of previous concepts already taught.

ACSL Senior/Intermediate Finals Review Session 3

Today, we reviewed for the shorts portion of ACSL Senior and Intermediate Finals by completing miscellaneous problems that have shown up on past contests.

ACSL Senior/Intermediate Finals Review Session 4

Today, we reviewed for the shorts portion of ACSL Senior/Intermediate Finals by completing miscellaneous problems that have shown up on past contests. We also practiced solving programming problems from past years' all-star contests.
