Candidates performance was affected by the following weaknesses:

• poor computational skill;
• poor comprehension on application of principles;
• poor knowledge of organic chemistry;
• lack of adequate knowledge of some concepts e.g half-life, covalent bonding;
• inability to correctly write some organic equations and structures;
• usage of unconventional symbols of elements such as AL instead of Al; fe instead of Fe;
• inadequate understanding of solubility, functional group, activation energy and activated complex;
• poor study habits;
• inability to balance chemical equation.

The following remedies were suggested to overcome these weaknesses:

• adequate and effective coverage of syllabus;
• more exposure to practical work;
• parents to provide relevant textbooks and ensure that they make use of them adequately;
• instructional materials should be provided by schools/improvised by teachers for effective teaching and learning;
• schools should engage qualified teachers;
• government to popularize the study of science;
• Chemistry teachers should be mandated to attend coordination meetings to gain more experience.
