What drives you crazy?

The week of exams drives me crazy,because it is very exhausting.I usually attend study groups,so I stay at college every full day from this week.We need to review a lot concepts and information for the exam.I go to the college around 6:50 a.m and I go back home around 8 p.m after I finish the preparation for the test.The other thing,that drives me crazy,is to wake up early with the sound of the alarm clock.Whem this occurs I have an awful day.I don´t like the sound of my my alarm clock,because it is too loud.
