Firstly, examination is the best way to rate your knowledge. If you know enough it would not be a problem for you. In my opinion - there is no disadvantages. Just relax and write or speak what you learned.
To be a teenager is very difficult and everyone has different problems. One of them is schooling- the attitude of classmates' or teachers' to them. To come over these problems teens should try to be calm and respect parents. For example I'm also a teenager but I have never done anything stupid to look cool in front of my friends. Bad habits like smoking, drinking, taking drugs can not be cool! So this is nonadequate self-esteem. Too much pressure is put on me by my teachers and parents but I don't get annoyed with theirs behavoiur. I know a lot of boys and girls, who think that cleaning their room is the most important problem of humanity. They think it’s boring and useless. So they should change their lifestyle to have better life because the teenager years are happy stage in our life.
