Frequently asked questions

Short answers about this page.

Which Math AA HL exam sessions are covered for 4.14 Continuous random variables (HL only)?

12 sessions from 2021 to 2026, the latest May 2026. Every Paper 1, 2 and 3 in every timezone is read and classified in full.

Which 4.14 Continuous random variables (HL only) topic comes up most?

Continuous: mean, median, mode, variance (4.14.3): in 26% of sittings, last seen May 26 P2, usually a "find / solve" question worth about 3.2 marks.

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 practice questions of the same shape 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.
