Frequently asked questions
Short answers about this page.
Which ESS exam sessions are covered for 3.3 Conservation and regeneration?
18 exam sessions from 2017 to 2026, the latest May 2026. Every Paper 1 and 2 in every timezone is read and classified in full, which gives 31 papers in this archive.
Which 3.3 Conservation and regeneration topic comes up most?
Values and conservation choices (3.3.9): in 14% of papers, last seen May 26 P2 TZ3. Usually "Evaluate / Suggest", worth about 6.7 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.
