Chemistry Paper 3 WASSCE (SC), 2018

Candidate's Weakness with Suggested Remedies

 

Candidates’ weaknesses in the paper were evident in the following areas:

  • majority of the candidates did not adhere to the instructions;
  • inability to differentiate between molar mass and relative atomic mass;
  • application of wrong unit;
  • inability to calculate mass concentration of solution;
  • inability to identify colours;
  • some candidates wrote clear solution instead of colourless solution;
  • application of theoretical approach to practical questions;
  • majority of the candidates carried out qualitative analysis on solid samples.

 

THE FOLLOWING REMEDIES WERE SUGGESTED FOR OVERCOMING THE WEAKNESSES

Candidates should:

  • understand the demands of the questions before responding to them;
  • improve on their communication skills;
  • be familiar with the examination syllabus;
  • learn how to write and balance chemical equations correctly;
  • learn how to write IUPAC names of compounds correctly;
  • improve on their study habit;
  • qualified teachers should be allowed to teach the subject.
