Before the exam, for like a few weeks, go to bed early and eat well. Also do practice exams if you can, that way everything becomes familiar so in the real exam you'll be comfortable with doing them. Also don't study every day, take a day off or you'll explode, and study in 20 minute time slots, taking a break between each because the longer you study without a break the less alert you become and the less information you take in.
As for the stress, the practise will ease that and, on the day, be really positive, make your mates positive and have a generally good atmosphere around you. Ty breathing exercises before you go into the exam and listen to some of your favourite music before going in, it's always good to have your favourite song going through your head in an exam.
