Напишите небольшое рассказ.  Exciting moment in school  (ответить в нем на вопросы:  что случилось? как ты себя чувствовал?)

Yesterday we should have two final test, one of them was in chemistry. I hate it, i don't understand the purpose of learning it. I expected this test not to be, i had butterflies in my stomach (если что - это идиома), i couldn't concentrate. Thanks God the lesson was delayed - the teacher had got ill. It was a narrow escape! Удачи, бро! :)
