Key #3 for test success
Key #3: Focus on your weaknesses.
It may seem obvious but it is true: successful test-takers focus on areas of weakness. Identify your areas of weakness and practice them until they seem 'not so hard' anymore. Of course, this takes time, but you cannot bury your head in the sand...
Be realistic about your strengths and weaknesses. Solve the problem(s) and enjoy the reward of success!
