I can count to 6

I got all the emails out that I needed to today! I was pretty pleased with that, anyway. Now I am mopping up the fallout. I'm working tomorrow to fix the errors and problems.

After I had sent the emails out to the students, I got a call from a student about a problem with his math exam
Him: On the email you sent me I only got 5 hours to write the exam, but I am supposed to get 6 hours
Me: (looking up his accommodation) Yes, that is correct, you should have 6 hours, what time does the email say that you get?
Him: 9am-3pm
Me: That is 6 hours
Him: Ohhh, this does not bode well for my math exam!!!
