Frequently asked questions

Short answers about this page.

Which Math AI SL exam sessions are covered for Unit 1: Number and Algebra?

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

Which Unit 1: Number and Algebra topic comes up most?

Arithmetic sequences (1.2.1): in 25% of sittings, last seen May 26 P2 TZ3, usually a "find / solve" question worth about 2.2 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.

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.
