  • Read efficient textbooks and also ensure to read the textbooks that explain better, that enables you to grasp the subject matter very well.

Method 4

  • First, choose the easy topic that you know you can understand properly within a twinkle of an eye. You should complete the easy topic first, you can complete this in no time.
  • After that, first, try to read the book and take short notes on that book.
  • If you are preparing for waec exam, they sit down and analyze past questions of waec to see the format in which waec sets its question.
  • Focus more on those topics that are repeated frequently in the past questions.
  • Don’t be a jack of all trade by trying to remember everything. Instead, you should understand the concept, once you understand the concept, you can put it down in your own way.
  • Ensure you take short and long breaks while studying.
  • Engage in meaningful conversation with your friends to share knowledge and gain more knowledge since nobody is a mountain of knowledge.
  • Ensure you don’t stress your brain too much by loading it with knowledge even when you ought to be sleeping. Ensure you sleep when you ought to.

There will be two papers both of which must be taken for a total mark of 160. Candidates will be allowed an extra 15 minutes for reading Paper 1 during which they are not expected to write anything.

PAPER 1: will be a practical test lasting 2¾ hours comprising three questions out of which candidates will answer any two to score a total mark of 50. The paper will be taken by school candidates only. Each question of this paper will have two parts: A and B.

(1) Part A will be an experiment for 21 marks. Candidates will be required to state the precautions taken during the experiments and reasons for such precautions.

(2) Part B will consist of two short-answer questions that are related to the experiment for 4 marks.

PAPER 2: will consist of two sections: A and B which will last for 2¾ hours.

Section A will comprise 50 multiple-choice objective questions drawn from the common areas of the syllabus. It will last for 1¼ hours for 50 marks.

Section B will last for 1½ hours and will comprise of two parts: I and II.

This will be tested by a practical examination based on the syllabus. The objective of the practical examination is to test how well the candidates understand the nature of the scientific investigation and their capability in handling simple apparatus in an experiment to determine an answer to a practical question. It is also to determine their competence in demonstrating their understanding of some of the principles involved in a small-scale laboratory experiment.

The practical test will contain enough instructions to enable candidates to carry out the experiment. Even when standard experiments, such as the determination of focal lengths or specific heat capacities are set, candidates will be told what readings to take and how to calculate the result. Therefore, it should not be necessary for candidates to learn by heart how to perform any experiment.

In addition to experiments on the topics in the syllabus, candidates may be asked to carry out with the aid of full instructions, variants of standard experiments. Candidates should be trained to take as varied a set of readings as possible and to set out the actually observed readings systematically on the answer sheet. The experiments may require a repetition of readings and an exhibition of results graphically and their interpretation.
