The weaknesses associated with candidates’ performance include:

•  lack of understanding of the demands of the question;
• non-adherence to rubrics;
• poor presentation/communication skills;
• illegible handwriting;
• spelling errors;
• inability to write chemical formulae accurately and  balance chemical equation;
• inability to answer questions on biotechnology;
• poor knowledge of electrochemical cell and it related calculations;
• poor knowledge of redox reactions.

             The following remedies were however suggested

•  candidates should familiarize themselves with the required syllabus;
• teachers should emphasize on areas of the syllabus where candidates appear to be weak such as electro chemistry, redox reaction and nuclear reaction;
• candidates should acquire relevant text books;
• experts/professionals should be employed to teach the subject;
• teachers should be encourage to attend/participate in marking coordination to update themselves.
