A test must contain at least one test section and at least one question. You create test sections to organize the questions drawn from a question bank. If your test has multiple sections, you can specify the order in which the sections are displayed to the learner in the test. However, you can determine a section order only if you have selected the Fixed option in the Section Order field in the test properties. If the Random option has been selected for the Section Order field in the test properties, the test displays a different order of sections on each learner attempt
Once you make a test available to your learners, and at least one learner has taken the test, you cannot delete the test section (or the test), since this affects learner performance and test statistics on your production system. If one section becomes invalid, but the test itself is still available, make the section inactive, instead of deleting it. Unpublish a test to make the complete test unavailable to learners. Past performance and test statistics information remain in the system when you unpublish a test.
