Problem:

Some exams last longer than 2 hours.

Cause:

Students are given 2 hours of exam time – exam time is counted as the time taken to answer questions.

To ensure fairness this time limit is only on time taken to answer questions.

Any time taken to move from one question to another is not counted.

If an exam takes time to move between questions this time is effectively added to the exam time.

Additionally, if an exam crashes then the time taken to restart the exam is not counted in the exam time.
