I prepare slides for each topic providing a step-by-step explanation of concepts with diagrams and/or simulations. Each topic is qualified with exam-style questions and I emphasize keywords providing the correct approach for answering questions. I follow the guides prescribed by the board of education to prepare my lessons taking care of the depth and breadth of topics. Depending on your needs I would emphasize on the content or exam prep and make sure you not only ace the next big exam but also fall in love with the subject!
I have experience teaching advanced Biology and Chemistry in HKDSE (Hong Kong) and International Baccalaureate schools (Dubai) with my students averaging above 70% in both curricula. With my experience, not only do I understand the topics but also understand the dynamics of student-teacher interactions which allows for great targeted development.
