How To Get Highest Marks In An Exam

I would like to suggest some permanents strategies you can apply before you start your exam

Understanding
Seek to comprehend the ideas and methods taught daily so you do not need to cram for the exam.

Preparation
Do an adequate amount of preparation for the exam by reviewing the work and methods you have learned.
Get plenty of sleep the night before the exam.

Relax
Come to the exam in a relaxed mood and confident in your preparation.
Close your eyes and clear your mind for a minute or two just before the exam begins.

Distraction
Dont be distracted by the parasites, if I say parasites I mean some friends of your that would want to giraffe your work ,they will actually delay your brain and this  may bridge the time you have budgeted for your exam
