From 2023, two papers of 1 hour 45 minutes and 75 marks, 50% each: Paper 1, Computer Systems, on topics 1 to 6, and Paper 2, Algorithms, Programming and Logic, on topics 7 to 10. The last question on Paper 2 is a 15-mark scenario-based question, which the syllabus expects to take 30 minutes.
They are set on the earlier syllabus: Paper 1, Theory (1 hour 45 minutes, 75 marks, 60%), and Paper 2, Problem-solving and Programming (1 hour 45 minutes, 50 marks, 40%), of which 20 marks were questions on pre-release material.
