Curriculum


Prerequisites

  • Core CS assumes the student has already taken high school math, including algebra, geometry, and pre-calculus.
  • Advanced CS assumes the student has already taken the entirety of Core CS and is knowledgeable enough now to decide which electives to take.
  • Note that Advanced systems assumes the student has taken a basic physics course (e.g. AP Physics in high school).

Intro CS

Introduction to Programming

If you've never written a for-loop, or don't know what a string is in programming, start here. This course is self-paced, allowing you to adjust the number of hours you spend per week to meet your needs.

Topics covered: simple programs simple data structures

Courses Duration Effort Prerequisites Discussion
Python for Everybody 10 weeks 10 hours/week none chat

Introduction to Computer Science

This course will introduce you to the world of computer science. Students who have been introduced to programming, either from the courses above or through study elsewhere, should take this course for a flavor of the material to come. If you finish the course wanting more, Computer Science is likely for you!

Topics covered: computation imperative programming basic data structures and algorithms and more
