This WAEC/ GCSE ‘O’ Level Chemistry course outline is presented as a general guide and has been structured over twenty sessions. Please be aware that the depth and pace of the course content can be adjusted to cater to each student’s unique needs and prior understanding. This layout presumes a basic understanding of chemistry and may, therefore, vary for beginner students or those who are more advanced.


In addition, the course content can be individually tailored to suit each student or group, providing an accommodating approach for learners at all levels. This flexible approach makes the course adaptable for full-program students and those in revision programs.

This proposed course outline encompasses the major topics in a WAEC/GCSE ‘O’ Level Chemistry syllabus. However, it should be adjusted based on the specific examination board and any recent changes to the syllabus. Regular assessment of student progress should also be carried out, and the course structure should be adjusted accordingly to address any areas of difficulty.
