**How to Answer WAEC Mathematics Questions**

They are quite good number of students who have concluded that mathematics is one of the hardest subjects to write in WAEC examination. This could be as a result of how they were thought in their respective secondary schools. Some of them do not even have a good knowledge of mathematics.

For one to pass mathematics examination at one sitting in WAEC, they are some principles that must be put in practice. These are the rules that are applicable during the time of writing the examination.

If you follow the guidelines that I am going to give you in this section, then you will make an excellent result in mathematics

The principles for answering WAEC mathematics examination include the following:

**Read Instructions**

Once you have settled to take your examination in the examination hall, the next thing that you must do first is to read through the instructions on top of the page before you can proceed with reading the questions.

Most times, some instructions are specific to some questions, maybe one or two questions. Here, you still have to take those instructions very serious.

**2. Read Carefully**

Before you can proceed to answering WAEC mathematics questions, it is highly recommended that you read carefully to understand any question before you can start to answer the questions.

It is possible to see questions that would be similar to what you have been seeing before, probably in past questions, but they are not the same.

This is the point where it is very necessary that you meticulously go through the question before you answer, to avoid choosing the wrong option for objectives and giving wrong explanations for theory questions.

**3. Take Note of Compulsory Questions**

In every WAEC examination, there is/are usually some questions that are specially made compulsory by the West Africa Examination Council. These questions are always seen in the core 1 which is theory aspect of it.

You must ensure that you are able to answer those compulsory questions before you can think of answering any other ones. The compulsory questions do carry special mark.

**4. Start with the Simplest**

The complexity of every question in WAEC mathematics varies. After you have gone through the questions, you would be able to tell which of the questions are simple and the ones that are difficult.

The best approach in such case requires that you answer the questions from the simplest to the most complex ones. This is important because it will help to cushion you against examination tension.

Not only that, it also helps in the management of your time. If you are finding any question difficult to answer, you have to leave it and go to the next. Thereafter, you can re-visit those questions that you have left unanswered.

**5. Attempt all the Question**

Though it is advisable that you start answering your question from the simplest, leaving the more difficult ones at the first attempts, it does not imply that you should submit you examination without answering those ones you skipped.

It quite understandable that you may not know all the asked questions, you are still required choose your answers even the ones that you do not really know very well.

Sometime, your guess can fall in place and become the right answer. So always ensure that you attempt all you question before you submit.

**6. Review your Answers**

After you have attempted the entire given questions, you still have to go through all the answers to check for any errors and possible corrections.

By going through the questions, you would be able to see any skipped question(s), if any and the ones you mistakenly clicked the wrong options.

**Reasons for Poor Performance in mathematics**

Many students have erroneously assumed that mathematics is the toughest subject that one can write on WAEC examination. Failure to perform excellently in WAEC mathematics examination is a question of whether the candidate knows the right things to do and if he/she is doing it right.

The poor performance that have been seen in some candidates’ results over the years are as a result of poor application of the basic principles for writing WAEC mathematics examination and some other factors that I am going to show you here.

**1. Inadequate Preparation**

This is the most important aspect of the reasons for poor performance in WAEC mathematics that should be considered.

It is obtainable in all areas that when there is poor preparation for any examination they will be poor result. As a good student, you are required to prepare for the WAEC mathematics examination to the point that you would be sure of scoring high.

**2. Poor Time Management**

Time management is another important factor that can lead to poor performance in every examination. You should learn how to manage your time especially when you are in the examination hall.

The practice of time management starts from the period of the candidate’s preparation for the examination. Once you can answer your past questions comfortably with the limited time that will be provided, you will still manage your time very well on the examination date.

3. **Lack of Adherence to Given Instructions**

There are some students who are fond of ignoring instructions when come for examination. Jumping into answering of questions without reading the given instructions is very wrong. This contributes in a big way to poor performance in the examination.

If you want to have good performance in WAEC mathematics, you have to strictly pay close attention to any given instructions.

**4. Submitting Incomplete Answers**

When a candidate submits the examination without attempting all the questions, it will automatically affect his/her score. It is important you answer all the questions before your submission.

**WAEC Mathematics Theory Questions for 2023**

1. Copy and complete the table of values for the equation y = 2×2 – 7x – 9 for -3 ≤x≤6.

X | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 | 5 | 6 |

Y | _ | 13 | _ | -9 | -14 | _ | -12 | _ | 6 | _ |

1. Using scales of 2 cm to 1 unit on the x-axis and 2 cm to 4 units on the y-axis, draw the graph of y = 2×2 – 7x-9 for -3 ≤ x ≤ 6.

2. Use the graph to estimate the:

3. roots of the equation 2×2 – 7x = 26;

(ii) (iii) coordinates of the minimum point of y; range of values for which 2×2 – 7x < 9.

**Question 2**

Marks | 1 | 2 | 3 | 4 | 5 |

No. of students | m+2 | m-1 | 2m-3 | m+5 | 3m-4 |

The table shows the distribution of marks scored by some students in a test.

1. If the mean mark is 3 , find the value of m.

2. Find the:

(i) Inter-quartile range;

(ii) Probability of selecting a student who scored at least 4 marks in the test.

**Solutions to WAEC Mathematics Theory Questions 2023**

A solution to Question 1

**Step 1: Complete the table**

X | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 | 5 | 6 |

Y | 30 | 13 | 0 | -9 | -14 | -15 | -12 | -5 | 6 | 21 |

**Step 2: Plot the graph using the given scale (2 cm to 1 unit on the x-axis and 2 cm to 4 units on the y-axis)**

**Step 3: Obtain the root of the equation**

The roots of the equation 2×2 – 7x = 26 were obtained by drawing a line through y = 17 to meet the curve y = 2×2 – 7x -9. The required roots are – 2.2 ± 0.1 and 5.8 +0.1. The coordinates of the minimum point of y is 1.8 ± 0.1, -15 ± 0.4. The ranges -1+0.1<x<4.5+0

**Solution to Question 2**

**Step 1: find the value of m**

x | 1 | 2 | 3 | 4 | 5 | Total |

F | m+2 | m-1 | 2m-3 | m+5 | 3m-4 | 8m-1 |

Fx | m+2 | 2m-2 | 6m-9 | 4m+20 | 15m-20 | 28m-9 |

From the table** ∑fx = 28m-9 and ∑f = 8m-1**

So that, **28m-9/8m-1 = 75/23**

**∴ m = 3**

x | 1 | 2 | 3 | 4 | 5 |

F | 5 | 2 | 3 | 8 | 5 |

Cf | 5 | 7 | 10 | 18 | 23 |

**Q _{1} = **(23+1/4)th position = 6

^{th}position = 2 and

**Q _{3 }**= 3(23+1/4)th position = 18

^{th}position = 4

∴ Interquartile range = 4-2 = 2

(ii) the probability of selecting a student who scored **at least 4** mark is 13/23 whereas most candidates made use of **at most 4 marks** is 18/23
