Marked only by official IB examiners

Paper 3 is the last paper Higher Level Computer Science students will sit. In this post, we’ll provide a thorough breakdown of IB Computer Science Paper 3, ensuring you are familiarised with the structure of the exam and know what type of questions to expect. 

 

 

IB Computer Science Paper 3

 

 

  • Paper 3 is sat by HL students only.  
  • Paper 3 is made up of four compulsory questions based on a pre-seen case study.
  • Paper 3 accounts for 20% of the student's final grade. 
  • Students have 1 hour to complete Paper 3.

 

Each year, the IB publishes a detailed case study that forms the basis of the exam. While the specific questions change annually, students can generally expect a consistent question format.

 

Paper 3 questions may look the following way:

 

1. Explain the concept: hidden surface determination [2 marks]

 

2. Compare morphing to stop motion animation [3 marks]

 

3.  How could society benefit from improvements in real-time rendering leading to photorealistic CGI? [6 marks]

 

4.  Compare three different rendering techniques that can function on the PCs that are likely to be in the Pacific FX offices [6 marks] 

 

 

How to succeed in Computer Science Paper 3?

 

Succeeding in IB Computer Science Paper 3 requires a thorough understanding of the pre-released case study, as this exam is entirely based on it. Students should start by carefully reading and analyzing the case study document, identifying key terms, technologies, and concepts mentioned. It is also essential to research related IB Computer Science topics that might apply to the case study scenario. It is very important you know the case study very well and are able to approach it from various perspectives before the exam. Creating notes, summarizing important points, and discussing the case study with your friends can help to really solidify your understanding of the case study.

 

Practicing past Paper 3 questions and studying previous case studies is another crucial strategy for success. Since the structure of Paper 3 remains consistent each year, looking at past case studies and using them to answer corresponding exam questions can help students recognize patterns in the types of questions asked. This also allows students to learn to structure their responses and apply relevant concepts within a real-world scenario. 

 

On exam day, time management is key to maximizing marks. Since Paper 3 is only one hour long, students should allocate time wisely – spending a few minutes planning their responses before writing. It is very important to always refer back to the case study when answering questions, as this ensures that responses are relevant and directly linked to the given scenario. Examiners expect students to apply their knowledge within the specific context provided, rather than giving generic answers. The final, extended-response question often carries the most marks, so students should ensure they provide a well-structured, logical, and detailed argument, considering different perspectives.
