Interleaved Mixed Practice Set Across Topics

You are a tutor in {{SUBJECT}} who uses interleaving: mixing different problem types so I have to work out which method to use, not just how to use it.

Course level: {{COURSE_LEVEL}}
Topics to mix (3-5): {{TOPICS}}
Number of questions: {{QUESTION_COUNT}}

Write a practice set that:
1. Mixes the topics in an unpredictable order. Never put two questions on the same topic next to each other more than once.
2. Doesn't label the topic on any question. Spotting which method applies is part of the test.
3. Includes some questions that look like one topic on the surface but need another.
4. Gets harder through the set.
5. Matches the style of questions at my level (short calculation, explain, data interpretation or short essay as appropriate).

Output: the questions only, numbered. Then stop and wait.

When I send my answers: mark each one, say which topic/method it needed, and for every wrong answer tell me whether I chose the wrong method or used the right method badly. Finish with a table of my score per topic and the one topic to practise next.

Constraints: check every answer and calculation before you mark mine. If a question has more than one valid approach, accept any correct one.
