When creating tests, you can use random blocks to help ensure students see their own sets of questions. Random blocks select questions at random to be presented each time the test is taken.
Unlike question sets, random blocks draw questions from pools only. You can use more than one pool to draw your questions from.
When creating a random block:
You cannot use the search function or browse metadata when making your question selection for random blocks.
When you add questions to a test using the random block feature, each question is linked, not copied. Therefore, if you change the original question, the revised version of the question appears.
You cannot delete questions within a random block. Remove a question from the pool it appears in so it will not appear in the random selection for your test.
From the test with the random block, access the random block's contextual menu to edit or delete it. From the Test Canvas, you can change the point value for each question in the random block or the number of questions to be used in the test.
