Students can be well prepared for an exam but still fail.
Students should do the following during exam time for them to pass exams.
Avoid panic
It's natural to feel exam nervous prior to starting exams. But getting excessively nervous is counterproductive as you will not be able to think clearly.
The best way to manage this is to close your eyes and take long, slow deep breaths.
Breathing will cool your nervous system.
Read instruction careful.
Quick survey each question on the question paper, read instruction for the second time to see the questions you are supposed to answer. Prioritize what need to be done. Put a mark beside all questions you know your can answer.
Divide the time according to the need of the questions. Answer the easiest questions first to guarantee marks in a few minutes.
Pace yourself. Don't rush through the exam, regular check time and make sure you give yourself time to proofread.
