How to prepare for WAEC Mathematics Essay & OBJ Exam 2019? - Question & Answer

Before we go on to give you the Questions and answers on WAEC Mathematics, let us first of all guide you on how you can prepare and pass with good scores and As.

Passing this subject is very simple, it all depends on how you will see because what we understand here is that WAEC is not setting the questions so that candidates will not have the answers. What we mean is that they are not hard.

You simply need to follow the tips given below and everything will go straight throughout this period of WAEC.

#1: Put God First

Everything one has in life has been pre-destined for one to have. Nothing happens by chance, you need to recognise your creator and giver in everything you want to do.

Put God at the top of your priority while preparing for WAEC Mathematics Answers. He can do all things.

Have you ever heard someone complaining of not remembering what he or she read in the test hall? Has it ever occurred to you? If yes, then, the solution to this is for you to recognise your creator and tell him that you've handed everything into his hands.

#2: Set up your Reading timetable and Study Extensively

Once you have prayed to God, the next thing is to start reading immediately. Laziness is not a friend to anyone at all.

How do you start your reading? The first thing to do is to schedule your time, that is, prepare a timetable for your studies.

You must make sure that it favours you and that you'll not miss it for anything. Whether it is at night or day time, the most important aspect is to schedule when you are free.

Once you're done with that, begin the reading work very seriously. Look for the quietest area and hide.

#3: Study with WAEC Syllabus for Mathematics (Math Expo)

Most candidates make the mistake of just reading their books like a novel. No, you want to get this subject into your head, then you must read it with care. Read as if you want to know.

Studying without a syllabus especially for WAEC Mathematics question and answers will not help you at all. The syllabus is there to guide you on the topics you are to read. It will also give you the subtopics and will direct you properly.

So, we advise you to use WAEC Syllabus for Mathematics if you really want to get an idea of how the questions and answers will look like.

In spite of the provisions made in paragraphs 4 (1) and (2) above, it should be noted that some questions may prohibit the use of tables and/or calculators.

#4: Use WAEC Recommended Textbooks for Mathematics (Math Expo)

There are some recommended textbooks you should use while studying. You can search it online or ask your teacher in the school to give you the best textbooks to use for WAEC Mathematics exam.

He'll be very delighted to hear that and will give you without wasting any time.

#5: Do not Miss classes

You should not miss classes so easily if you want to pass WAEC Mathematics questions with correct answers. This is because most of those things your teacher will say will appear in the exams and that will be of great help.

Remember, one mark can change your story in WAEC. So, do not joke with lectures when it is time.

Again, you can pay a tutor to take you after the normal school hours, it helps a lot. This will give you the confidence that you need to write your exam without shaking.

# Say no to Malpractice

Malpractice does not help anybody. If you cheat and pass today, a day is coming when you shall not be able to cheat. What you know shall be required of thee.

Therefore, it is pertinent you write it on your own and forget about malpractice. Remember, a little form of misconduct can lead to the cancellation of WAEC Mathematics exam in your centre. Write the questions and get your answers correctly without involving in any problem.

With these tips, we are convinced that nothing will happen to your answer sheet at all and you'll pass successfully if you adhere to it.
