Chemistry Paper 3 WASSCE (SC), 2022

Candidate's Weakness with Suggested Remedies

 

Candidates’ weaknesses were as follows:

-           manipulation of titre values to agree with those of the teachers;
-           wrong units;
-           poor mathematical skills;
-           inability to differentiate between significant figures and decimal places;
-           poor reportage of experimental findings;
-           poor knowledge of activity series.

 

THE FOLLOWING REMEDIES WERE SUGGESTED FOR OVERCOMING THE WEAKNESSES

-           candidates should learn the difference between decimal places and significant figures;
-           more practical activities should be carried out before WASSCE begins;
-           candidates should learn how to write inferences from observations;
-           candidates should learn how a mole ratio could be deduced from a reaction equation.
