Question Pools are parts of Exercises. They can have any number of Questions put in them, and they will randomly select the number of questions assigned on the Pool Page. All questions that are sampled from a pool are given the weight assigned on the same page.
Question Pools have two primary benefits:
- Professors can put a subset of a large pool into an exercise by making the Number of Questions to Select smaller than the number of questions in the pool. This can create diverse exercises where different students taking the same exercises do not see the same combination of questions while making sure they answer the same number of questions and have the same number of total marks available.
- Professors can make questions appear multiple times in an exercise without needing to write the same question multiple times by making the Number of Questions to Select larger than the number of questions in the pool. By including Formulas in the questions, this can be used to easily generate many questions that are distinct but still follow the same structure.
