Change the way you think about examinations. An exam is very important and good results are important as well, but a single test or exam cannot determine your future or success in life. It is the accumulation of years of dedication and hard work that can bring you success.
Do not become discouraged or overwhelmed if you do not receive the score you worked for. It simply means that there are areas which you can improve on.
Remind yourself that it is only an exam and there will be others to prove yourself. When you have improved, but aren’t quite there yet, remind yourself of all the progress you have made so far. Reward yourself after the exam if you have studied hard. Stay motivated and plan ahead.
