How To Answer NECO Physics Objective Questions [Section A]

NECO section A contains Objective Questions of 4 or 5 different options. In case, how do you choose a correct Answer form this 4 or 5 options?

To the correct Answer form those different options, follow the steps below:

1. Read a particular question more than once before trying to choose an answer.

2. Answer the questions you know first.

3. Imagine and try recalling what the correct answer is.

4. Pay particularly close attention to words like “notsometimesalways, and never.” An answer that includes always must be irrefutable. If you can find a single counterexample, then the answer is not correct. The same holds true for the word never. If an answer option includes never a single counterexample will indicate the answer is not the correct.

5. Eliminate each clearly wrong options that you know that are odd.

6. Using the process of elimination, cross out all the answers you know are incorrect, then focus on the remaining answers. Not only does this strategy save time, it greatly increases your likelihood of selecting the correct answer.

7. When two answers are correct in a multiple choice question with an “All of the above” option, then it’s probably the correct choice.

8. If all else tactics fails, then guess like a street magician and you may get it right.


How to Answer NECO Physics Theory Questions [Section B].


NECO Theory Questions are not the same as the Objective Questions. NECO theory exam questions can sometimes be  intimidating especially when you have no self-confidence.

The first thing you have to do when you are about to answer NECO theory Questions is to eliminate fear and believe that you can make it..

NECO theory Questions always come in different forms and format and each format needs a unique and correct answer.

To Answer any NECO theory question, follow this steps.

  1. Go through the exam’s instructions first before you start answering its questions.
  2. Read a particular question twice or thrice before you give and answer
  3. Understand each question and what the examiner is really looking for.
  4. Start your answer by echoing the question if it is an essay question.
  5. Go through your Answers to make sure all your writings and answers are well spelled and accurately presented.

NECO Physics Theory Exam Answers Structure 2020

When answering theories or Essay questions, take note of the following and how you should present your answers:

  • Describe: This means you should say what you see – no need for reasons. You can give a detailed account, using examples
  • State: Provide a factual report with no explanation or opinion.
  • List: Write down bullet points, not paragraphs. Keep it brief.
  • Explain: give reasons
  • Outline: give a brief summary
  • Analyse: go into detail
  • Compare: what are the similarities and differences?
  • Contrast: what are the differences?
  • Calculate: use numbers given to work out the value of something
  • Define: give the meaning of something
  • Evaluate: consider both sides – pros and cons
  • Justify: give evidence to explain something
  • To what extent: Judge the importance or success of something – has it worked or not
  • Argue: present a case with evidence or reasons
  • Assess: Weigh up / give an informed judgement
  • Comment on: give your opinion on something
