This course will reinforce students’ understanding of physics from A-level. It will encourage critical thinking by emphasizing on reasoning, understanding the relationship between concepts and seeing the relevance of physics to everyday life. It will teach strategies for problem solving that can be applied to real world situations. After the study, students will be equipped with the basic knowledge for further study in the broad field of engineering.
