An exam

3 students were having an exam but they didn't study for it, so they went to the teacher and said that they were driving and they had an accident, so they couldn't study for the exam and they hope to postpone (delay) the exam for 3 days. The teacher agrees, and after 3 days he made an exam for them and the questions were:
  (1) Describe your car accident.
 (2) When did the accident happen?
(3) Where did the accident happen?
(4) What did you and your friends do after the accident?
 

P.S. if all of your answers didn't match with your friends answers all of you will take ( F )
