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.
