For a long time Electrical Engineering students at the University of Dar es Salaam had negative attitudes towards Engineering Electromagnetics course. This is because the course is heavily loaded with mathematical concepts. The use of timed assessment was adopted for this course because it encourages the students to study widely in an attempt to cover wide range of concepts in the course. Another reason for using this approach was based on the consideration that students have to perform equally well in other courses. The timed assessment tasks are given frequently to ensure that students’ concentration on the cost is maintained. This paper presents how the use of timed assessment has enhanced students’ understanding of the Engineering Electromagnetics course and contributed to improved performance in the course. Trend analysis was conducted for students’ performance in the timed assessments given to them for the entire period of the course. This study advocates an increased correlation between the continuous assessment (coursework) scores and final examination scores effective from the year when the extensive use of timed assessment was adopted for the course.
