Examiners report

A poorly answered question with low discrimination factor. Several teachers asked whether this question of "cells in series" was in the Chemistry Guide (see Topic 19.1, Electrochemical cells, on page 96) and it is likely that this topic may not have been covered in class by some teachers.
