Some of the candidates were unable to:
 convert the raw values using the given scale factors to real values;
 manage the time allotted for the paper efficiently by recopying the questions;
 record measured/converted values to the required decimal places/significant figures e.g. E1,
V, L3, etc.
 plot points correctly on the graph to the required least squares especially those involving
large figures or decimal places;
 adhere to the prescribed format by plotting with raw values instead of converted values;
 use large rightangled triangle in the evaluation of their slope
 draw line of best fit correctly
 express themselves clearly in simple language;
 evaluate reciprocals and cubes to the required decimal places;
 state relevant precautions correctly.
The suggested remedies were as follows:
 Basic concepts in Physics should be thoroughly taught by Physics teachers;

More drilling exercises should be given to candidates on computational skills and graph;
 Mathematics teachers should assist candidates to master the plotting of graphs;
 Parents to provide necessary and adequate support (textbooks, reading tables and other
necessary materials);
 Schools should endeavour to equip their laboratories
 Teachers to organize adequate practical classes for candidates;
 Teachers to attend WAEC coordination and marking meetings to acquire more experiences.
