Mostly Repeated WAEC Past Questions and Answers on Biology

I believe that you’re here because you don’t know the nature of how exams are being set by WAEC. If you don’t, then you’re at the right place.

In this guide, we will talk extensively on WAEC past questions and answers for biology, show you possible questions that may likely fall into the exams paper in the proceeding year.

Not only that, you’ll be given adequate instructions on how to answer questions on WAEC

Recently, I wrote on two interesting topics WAEC Past Questions and Answers on Civic Education and WAEC Past Questions and Answers on Chemistry , I strongly recommend you to click on the links above and read.

The WAEC past questions and answers are mostly repeated year after year, which is why you have to read this guide carefully till the end and take notice of those questions.

Most times, I hear students giving complains about how hard the questions is, reason behind it is that they failed to study using our guide.

I believe if you’re reading this, you will definitely want to pass your exams with flying colours. See more details on the instructions and guidelines given by WAEC  to follow while writing the exams below.

Important Guidelines to follow in your WAEC Examination

There are alot of guidelines and instructions you as a student need to follow. We will bring to light what needs to be done accordingly.

The examination paper is divided into three different parts, which is Part 1,2 & 3

Part 1 is Objectives. You should expect 50 questions from this section.

Part 2  is the theory section, you should be expecting 10 questions to answer 5 from this section. This section carries the highest point.

Meaning that if you do well with this section and a little of part 1 ..then you’re good to go.

Part 3 is the practical section.

You should also note that the West African Examination Council frowns at cheating. Any candidate who is caught cheating will be sentenced to life imprisonment.
