Do I need to complete the course in one sitting or I can do it in multiple sittings over a period of time?

You can go back and forth to the articles and read them over many sittings over a period of time. You can also take the posttest in as many sittings as you wish, as you can save your completed answers each time. Once you reach a passing score of 75% or better you will not be able to retake the test.
