  1. Have a Timetable for Your Studies:

The WAEC examination is not the kind of exams that students just get in and perform well. You must have a decent timetable that outlines your reading schedule. This schedule should allocate adequate time for all your subjects.

  1. Forget about Waec Expo:

This is the reason why so many candidates fail waec. They depend on answers that will be sent to them on the waec examination day. Getting waec answers on the exam day is still very valid. You can get both waec theory and Objective answers in your inbox. However, they are not to be trusted. You can be a victim of wrong answers.

  1. Trust yourself

You should be very confident in yourself and believe that you will pass the exams. Though the exams are usually hard for students to pass, a confident student will easily pass the exams and proceed to the University. Therefore, students should exercise self-confidence before and during the exams.

  1. Don’t Procrastinate

Later things. This is the top language of procrastinators. You need to start anything you need to start so as to pass waec. Do not delay or surrender.

  1. Notes taking:

This is one of the most effective way of studying. During your allocated time for study, it is important to take notes on some important points. These notes might help you when doing a final revision for the annual WAEC exams.

  1. Revise Past Papers

While doing your revision, you should allocate good time revising the past papers. As a trend by the WAEC, examination tests are drawn from previous papers. They only twist the questions to get a new examination. Therefore, you should not ignore the past papers and actually take it as a preparation strategy to revise them.

  1. Read all the Examination Rules:

WAEC has strict rules that govern its examinations. You should thus read all the rules before getting into an exam room. Though the rules will be written in front of the question paper, some students fail to read them during examination period and thus show the importance of reading them prior to the exams.
