You can create a random block of questions and choose the number of questions to use for the test or quiz within the block. Your test can include one or more random blocks. If you use more than one random block, be careful not use the same question or a student could get the question two times, (once in each block) even when randomized. Using random blocks of questions can increase the security of your test or quiz by making it harder for students to share test or quiz answers.
