Next tuition session will be on 21 Nov, 0900 - 1100 hr at ITR 2. Do remember to practice drawing the lens ray diagrams. There's a worksheet on it in Moodle --> Independent Learning --> Optics. Download the ray diagram worksheet and see if you can draw them correctly. Do remember to draw the diagram for Diverging Lens as well. Do refer to your textbook.
During the next lesson, we'll be going through all the Optics questions in the textbook and TYS. The next chapter that we'll be revising is Kinematics. Hope this helps.
