How to revise Computer Science

Start with your class Google Site. Review notes, lesson resources, and revision materials your teacher has shared. All the resources you make and use should be added to your Google Site.

Revise theory topics regularly

• Make flashcards (Quizlet or paper) for key terms and definitions.

• Practise short-answer questions (1–3 marks).

• Use past paper questions from PMT or OCR.

• Watch Craig’n’Dave videos and summarise them in your own words.
  
  

Practise coding every week

• Use Google Colab or Trinket to run and test Python programs.

• Focus on: input/output, if statements, loops, lists, subroutines, file handling, and trace tables.

• Don’t just read code — run it, edit it, and test what happens.
  
  

Mix up your revision

• Make mind maps, diagrams, and flowcharts for theory topics.

• Try quick quizzes (Kahoot, Quizizz, CSNewbs).

• Teach a friend a topic — if you can explain it clearly, you really understand it.
  
  

Exam technique

• Practise full past papers under timed conditions.

• Study OCR mark schemes to learn what examiners are looking for.

• Review mistakes carefully — understand why you lost marks and how to improve next time.
