Note that the format of a basic question is not necessarily multiple-choice. The purpose of providing these basic questions is not to simulate the real exam. You can experience that feature when you take review or mock exams.

After you have seen a basic question, you may decide that you don't want or need to see that question again: it is may be too easy for you -- whatever the reason, you can recycle the question. The next time you start basic questions of an LOS, you can choose to either view only those questions that you have not recycled yet, or all of the basic questions for the LOS. Flexible and timesaving, right? You also have the option to restore any question you recycled to the question pool if you feel that you are missing something by its exclusion.
