Short answers about this page.
Which Geography SL exam sessions are covered for 7.1 Drainage basin hydrology and geomorphology?
15 exam sessions from 2019 to 2025, the latest November 2025. Every Paper 1 in every timezone is read and classified in full, which gives 12 papers in this archive.
Which 7.1 Drainage basin hydrology and geomorphology topic comes up most?

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.
