Candidates’ weaknesses include the following:

1. non adherence to rubrics;
2. spelling errors;
3. lack of mathematical/manipulative skills;
4. poor knowledge of concordance in precision measurement;
5. inadequate understanding of the mole concept and stoichiometric calculation.
6. lack of knowledge of significant figures;
7. inability to relate effectively observation with relevant inferences.
8. use of chemical formulae instead of the IUPAC names of compounds/reagents;

1. test on solids instead of solutions;
2. manipulation of titre values to agree with those of the supervisors.
3. omission /wrong use of units;
4. inadequate preparation.

The following were the suggested remedies:

• Candidates should familiarize themselves with the prescribed examination syllabus. 
• Candidates should be exposed to more laboratory practical/work.
• Qualified teachers should be employed to impart the requisite knowledge.
• Teachers of chemistry should attend seminars/workshops e.g. those mounted by STAN in order to be exposed to new frontiers of knowledge.
•  Candidates should prepare adequately for examinations.
