There's a timer you can toggle to simulate a testing environment. For every level it's an additional 1hr that is capped at 3:30hr for B+ intermediate. A and above do not get extensions. If timer runs out, answers including ommited questions will be calculated as percent of 100. On final question, for example question 200/200, if next is clicked on again, Quiz will calculate score. Cannot checkanswer until you answer the question. Changes to C level, its now a multiple choice for beginners
