⟡✦ Computer Science Courses ✦⟡

Pre-AP CS:
Web Development

The goal of the Pre-AP Computer Science course is to build a foundation in creative User Interface (UI) design through the exciting lens of Website Design & Development. Students review static website creation with HTML and dive into advanced CSS styling techniques. The programming language JavaScript is also introduced in the context of building interactive webpages, dynamic web applications, and browser games.

AP CS:
Java Programming

This course follows the College Board Advanced Placement curriculum for AP Computer Science A. The goal of the course is to design, analyze, and implement solutions to a wide array of problems using the Java programming language. The technical focus of the course is Object-Oriented Programming (OOP) class design and implementation. Students write algorithms with selection/branching, repetitions/iteration, and recursion.

Post-AP CS:
Python Applications

The Post-AP Advanced Topics in Computer Science course offers highly motivated students the opportunity to expand on topics covered in the Pre-AP and AP courses. Modern applications of the Python programming language are highlighted, including Data Science & Exploratory Data Analysis (EDA) with pandas/matplotlib/seaborn, dynamic web applications with Flask, database operations with SQL, and Machine Learning & AI.
