Draft Lecture Schedule
Teaching Strategies The teaching in this course aims at establishing a good fundamental understanding of the areas covered using:
Formal face-to-face lectures
Tutorials, which allow for exercises in problem solving and allow time for students to resolve problems in understanding of lecture material.
Laboratory sessions, which support the formal lecture material and also provide the student with practical construction, measurement and debugging skills.
Small periodic quizzes, to enable you to assess your understanding of the concepts.
Evaluation Strategies Cycle Test – I Cycle Test – II Model Test Assignment Attendance Final exam
