Graded IB Computer Science Notes Page
This page will store notes made by Mr. Griswold for students in IB Computer Science. It will be updated and edited over time, but old versions will be archived.
The material below is broken into three sections - general course resources, Paper 1, and Paper 2. Paper 2 is focused on java programming, but much of the thinking in paper 2 overlaps with topic 4 from Paper 1.

We will learn programming and problem solving in java using several resources - Coding Bat , CS Awesome , and CodeHS , and these notes will supplement those ideas.
- P2 1.1 - Anatomy of a method signature
- P2 1.2 - Variables and data types
- P2 1.3 - If statements, Return, and Logical Operators

Course Resources
Official IB Syllabus . In the notes, when a section connects directly to this syllabus, it will be represented with a superscript, like this .
CS Awesome . This is the primary online platform we will use to learn to program in Java.
Traced algorithms and coding problems . I will add coding problems and traced algorithms to this page, over time, for you to view and practice with.
CodingBat . Coding practice in java
CodingBat Pseudocode Practice - Coding practice in IB Pseudocode
IA Information
Sample IA Made in Class by Mr. G
The IB CS Guide - Includes the full syllabus (as a PDF, rather than the website above) and IA guidelines among other things
CompSciHub About page - This excellent resource put together by IB CS teachers and students compiles notes and information about the course.
Paul Baumgarten’s IB CS Page - Paul Baumgarten is a long-time IB CS teacher and active contributor to the community. His page includes notes and exercises on nearly all IB topics, as well as links to even more resources. The order is different than our course, but an excellent resource for studying or reading new perspectives.
Mr. Wach’s IB CS Page - Mr. Wachs is a teacher of many computer science courses including IB CS. He has many videos, slideshows, and workbooks that we will look at for some units, and makes a good resource for studying many aspects of the course.

IB CompSci Hub
Welcome to CompSci Hub
Welcome to the International Baccalaureate Diploma’s Computer Science resource site for teachers and students.
This site provides teaching & learning resources for eight key topics of the HL course (topics 1 to 7 and Option D – OOP). for the Computer Science course (either HL or SL) as a part of the IB Diploma .
Having scoured the web for information and resources regarding the Computer Science SL/HL course and found very little, I’ve decided to collate all known resources, add in a few of our own, and publish it for all to see and use. If I have accidentally used a resource that you own without your consent, please let us know and I will take it down immediately.
Regretfully, I no longer teach the IB Computer Science course. Furthermore, the IB has stated that they will be releasing a new specification to be started in the academic year 2023-24, with the first exams in May 2025.
Thank you to everyone for supporting this project for the last 7 years. I will miss you all dearly and wish you every success with your Computer Science journey.
Happy computing! Chris

Here are some steps you can follow to prepare effectively:
Study the syllabus: Make sure you understand the topics that are covered in the IB DP Computer Science syllabus. This will give you a clear idea of what to expect on the exams.
Review class notes and textbooks: Regularly review your class notes and textbooks to reinforce your understanding of the material.
Practice, practice, practice: Practice solving Computer Science problems as much as possible. Try to work through as many practice questions and Mock tests as you can find here at iitianacademy.com . This will help you get a feel for the types of questions you can expect on the exams and build your problem-solving skills.
Seek help when needed: If you’re struggling with a particular concept, don’t hesitate to ask your teacher or a tutor for help.
Stay organized: Make sure to keep track of important formulas, equations, and concepts so you can easily reference them when you need to.
Stay up-to-date on current events in Computer Science: Being knowledgeable about current developments in Computer Science can help you better understand the applications of the concepts you are learning.
