There are a lots of things that i have to prepare before i have an examination. Fisrt don't be a lazzy person when you're studying in class, yet be a good listener when your teacher is teaching you in class. then note down the important point in the lesson that you've studied. And go over the lesson every time that you've learnt. Do it every day around three months before the examination comes. but is you ware doubting about something in some lesson, you can ask your teacher anytime you want. When your examination is about closed, You should crammed the lesson with your friends and do often the exercise for practicing your skill. Yet you have to relax sometimes, Because your brain need to get rests enough for learning the new things. And one week before the examination comes, you have to stop doing anything, and make sure you get rests enough for examination. and above all you have to believe in yourself, and do it as good as you can do. be confident with your any answers you choose. It doesn't matter what will happen, you just do it by your fullest effort.
