Frequently asked questions
Short answers about this page.
Which Computer Science HL exam sessions are covered for 1.1 Hardware and operation?
14 exam sessions from 2026 to 2027, the latest Specimen 2027. Every Paper 1 in every timezone is read and classified in full, which gives 4 papers in this archive.
Which 1.1 Hardware and operation topic comes up most?
CPU components (1.1.1): in 18% of papers, last seen May 26 P1 TZ3. Usually "State", worth about 1.3 marks in a paper that includes it.
Can I see the original question and mark scheme?
No. The wording belongs to the IB. You get the citation, the marks, the command term and the skill tested, plus our own matched practice questions with worked answers and AI marking.
What do "banker", "due" and "rising" mean?
Banker: examined in at least one sitting in four and still appearing. Due: regular before, but absent for the last two exam sessions. Rising: clearly more common in the last two years. Our classification of real papers, not an IB statistic.
What is free and what needs Pro?
Reading this page and the exam pattern is free. A free account generates three sets of ten questions and launches one practice set. Pro opens every question in any scope, sets of twenty or all, and unlimited practice.
