Frequently asked questions
Short answers about this page.
Which Computer Science SL exam sessions are covered for 6.2 Data structures?
23 exam sessions from 2014 to 2027, the latest Specimen 2027. Every Paper 1 and 2 in every timezone is read and classified in full, which gives 28 papers in this archive.
Which 6.2 Data structures topic comes up most?
Arrays and lists (6.2.2): in 61% of papers, last seen Spec 27 P2. Usually "write down / state", worth about 5.2 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?
