Do you know why students are expected to take O level physics tuition from tutors teaching A and O-level physics? The reason is to have continuity. Students may believe that after O-Levels they will not take physics for their lifetime. The fact is life is unpredictable and the mind may change after the results of O-level physics.
There is an advantage in having O-Level to A- level same physics tutor and you may proceed with the same tutor to H3 Physics so that the continuity is ensured. Continuity allows scoring better results and also to have mastery over topics and the concepts are better understood.
