After the exam, we would advise you to resist the temptation to do a 'post-mortem' with your friends, only to find out that they answered questions differently to you and then start to panic. If you feel like things did not go your way, don't despair! You simply will not know until your results arrive how well you have answered the questions. From experience we can tell you that many times, the exam you think you have flunked in fact turns out to be the one you have smashed!
