Tips to Pass WAEC Computer Science Questions

1. Study Hard

It is known to everyone that hardwork brings success. Ensure to read the Computer studies textbooks recommended by The West Africa Examination Council (WAEC).

This will help you to take a look at most of the questions you will see in the day of WAEC Computer examination.

Let me clearly state that questions are not imported from heaven but from those textbooks recommended by WAEC.

2. Read WAEC Computer Studies Past Questions

WAEC usually picks questions from the previous years to form fresh questions. Studying WAEC Computer Studies past questions would give you an idea of how WAEC Computer questions are set.

3. Start Preparing for WAEC 2021 :

Stop wasting your time. Now that you have gotten textbooks and past questions, the next thing is to begin your reading. Early reading and practice is good for you; you will pass well on WAEC 2021 Computer Studies

4. Solve and try to understand every example and exercise you see in textbooks

It is very unfortunate that Secondary school students are fond of skipping exercises and even examples while studying textbooks.

They loved notebooks so much that they could ask, “can I read my Computer Studies notebook and pass WAEC 2021?”. Don’t be scared of attempting exercises; they are there to help you. Face it and overcome it!

5. Practise Regularly

Don’t get discouraged when certain topics are annoying, keep on practicing until you master everything. Never give up and never say never. Keep pushing….
