After the counter for an exam reaches zero the student selects to go to the Exam and is notified he / she is about to enter a times exam.
The  Exam UX is modelled and follows traditional "legacy" exam format.  Rather then questions appearing one by one  for the student to answer  then proceed to a new page,
all questiosn appear on one page.  This format allows students to quickly scan over answered questions correcting /  adjusting /  editing as needed. All while keeping an the timer.
