### About this course

**Are you a student taking the GCE “O” Level Physics examination? Are you having difficulties understanding the concepts in Energy, Work and Power and not able to follow what your teachers taught in school? If so, then this course is for you. **

**This course is carefully crafted to help students achieve the learning outcomes detailed in the GCE “O” level Physics syllabus (6091).**** It is designed to make the learning process simple, fast and effective.**

**Every lesson consists of a short video that explains the concept with animated illustrations using everyday-life examples. ****After each concept video lesson, ** quizzes with questions of gradual difficulty levels are provided to enable students to test their understanding and reinforce their learning. **A list of GCE “O” Level examination questions are also provided for you to try out. These questions test on the specific concept that you have learned. You will be amazed at how easy it is to solve them once you understand the concept. **

**Throughout the course, students will be given exam preparation tips, advised on commonly made mistakes and misconceptions and taught the skills of how to correctly answer GCE O Level questions. By the end of the course, students will be well equipped with the knowledge required for examination.**
