How to Answer WAEC Theory Questions to Get Full Marks: The Ultimate Guide

You know that feeling when you flip your exam paper to Section B, look at the questions, and your heart skips a beat? You actually know the answers. You studied hard. But somehow, when the results come out, the grade doesn’t match the effort.

It’s frustrating.

Here is the truth: Knowing the answer is only half the battle. The other half is presenting it in a way that makes the examiner fall in love with your script. Many intelligent students fail or get average grades simply because they don’t understand the “game” of marking schemes.

I’ve seen scripts where the student clearly knew the topic but scored 2/10 because they wrote an epistle when the question asked for a list.

If you want to smash your next exam, you need a strategy. In this guide, I’ll show you exactly how to answer WAEC theory questions to get full marks, using techniques that work for WAEC, NECO, and even university exams.

1. Understand the “Command of the Question”

This is where 60% of students lose marks before they even write a single word.

Every theory question starts with a verb. This verb tells you exactly what the examiner wants. If you miss this, you miss the mark.

• List/State/Mention: This means go straight to the point. Don’t tell stories. If the question asks you to “List 5 characteristics of living things,” just number them 1 to 5 and write them down. No explanations needed.

• Explain: This means “State the point + Give a reason/detail.” If you just list points here, you will get half marks.

• Discuss: This is the big one. This requires a detailed explanation, looking at different sides of the argument, and likely giving examples.

Before you put pen to paper, pause. Ask yourself: “What is this question actually asking me to do?”

2. The “Point, Explain, Example” (PEE) Method

For questions that ask you to “Explain” or “Discuss,” you can’t just drop a sentence and run. You need to flesh it out.

The best way to structure these answers is using the PEE Method:

1. Point: State your main answer clearly.

2. Explain: Elaborate on that point. Why is it true? How does it work?

3. Example: Give a relevant example (especially for Biology, Economics, or Geography).

Here is a practical example: Question: Explain the importance of agriculture.

• Bad Answer: Agriculture provides food and money. (This is too shallow).

• Good Answer (PEE Method): One major importance of agriculture is the provision of food (Point). It ensures that the population has access to essential nutrients required for growth and survival, reducing hunger in the country (Explain). For instance, crop production provides staples like yam and rice for daily consumption (Example).

See the difference? The examiner has no choice but to give you full marks for that distinct clarity. Developing this habit is one of the 10 effective study habits every student should develop.

3. Treat the Examiner Like a Tired Human (Because They Are)

Imagine being a WAEC marker. You have 500 scripts to mark in a hot room. You are tired. You are hungry.

Then you pick up a script that looks like a spider dipped its legs in ink and danced on the paper. The handwriting is tiny, the words are jumbled, and there are no paragraphs.

Will you have the patience to look for the correct answers? Probably not.

Make your work scannable:

• Use Paragraphs: Don’t write a solid wall of text. Break your points into short paragraphs.

• Leave Lines: Leave a blank line between each answer. It makes your work look neat and “expensive.”

• Handwriting: You don’t need calligraphy, but your writing must be legible. If they can’t read it, they can’t mark it.

A neat script psychologically tricks the examiner into thinking, “This student knows what they are doing.”

4. Start with Your Strongest Question

You do not have to answer the questions in the order they appear (Question 1, then 2, then 3).

Scan through the paper during the first 5 minutes. Find the question you know best—the one you can answer in your sleep. Start with that one.

Why?

1. It boosts your confidence immediately.

2. It sets a good first impression for the marker. If your first page is brilliant, the marker assumes you are a brilliant student.

However, make sure you number the question correctly! If you are answering Question 4 first, write “Question 4” clearly at the top. Don’t write “Question 1” just because it’s the first thing you are writing.

5. Don’t Be a “Ghost” on Hard Questions

Sometimes, you will see a question that looks like it came from Mars. You have no idea what the answer is.

Do not leave it blank. I repeat, do not leave it blank.

In WAEC and NECO, there is something called “attempted marks.” If you have an idea related to the topic, write it down in a structured way. Use the keywords from the question.

• Scenario: You forgot the definition of “Osmosis.”

• Strategy: Write down what you do know about movement of water molecules or cell membranes. You might pick up 2 or 3 marks. Those small marks add up to turn a C into a B.

For more practice on how questions are phrased, looking at past questions is vital. Even looking at common entrance questions can help younger students understand how examiners phrase things.

6. Keywords are King

Marking schemes are essentially lists of keywords.

When examiners mark theory questions, they are scanning your sentences looking for specific technical terms.

• If you are writing Biology, use words like “Photosynthesis,” “Enzymes,” “Habitat.”

• If it’s Government, use “Constitution,” “Democracy,” “Legitimacy.”

• If it’s Economics, use “Scarcity,” “Scale of Preference.”

Avoid street slang or overly casual English. You are a scholar in that exam hall. Sound like one.

Summary Checklist for the Exam Hall

• Did I read the instruction (Attempt 3 questions vs Attempt all)?

• Did I number my answers correctly?

• Did I use the PEE method for “Explain” questions?

• Is my handwriting readable?

Mastering how to answer WAEC theory questions to get full marks isn’t about knowing the textbook cover-to-cover. It’s about clarity, structure, and making the marker’s job easy.
