Exams

You don't need to worry about exams at the end of the year but don't be over confident, you never know what will happen. I found taking notes at the beginning of the year helpful because at the end if the year all I need to do is read all the notes again. You don't want to be doing all the studying the night before the exam, although you may remember stuff at the exam, it will not get into your long term memory. You don't have to revise through the year, but it's better if you do.
