Good A-level results result in early dismissal

Today was a great day. Rumours were flying that if the A-level results, which were to released today, were good, the whole high school would have an early dismissal.
11.10 a.m.- the fire alarm rang. We went to the hall where instead, our principal announced the great results. However, this joyous moment was marred by the fact that CCA was still on that day, meaning we could not go home. Also, our history teacher held us back for about half and hour to explain our holiday homework. Moreover, I had to see my chinese teacher.
Even worse, the weather was extremely hot and we had to do push-ups on burning hot ground. Still, it is the last week of school lessons as next week is sabbaticals.
