You can create multiple-choice exams, open-ended question exams and true or false exams.
Can I enter any topic for my exam?
Of course. You just need to make sure your topic is as specific as possible, For example, if you enter "Biology", that's not going to create a good exam, but if enter "Cell Wall and Cell Membrane", this will produce a better exam questions that will help you learn.
Can I enter any type of text when creating an exam?
Kind of... You can enter any text that's informative, so your physiology school material or your CompTIA Security+ material, so long as the text is informative, then than that will create the best possible exam questions for your revision!
