I was a fulltime school teacher and partime Medical Lecturer. I also provide online tuition for students and my goal is to keep students challenged. I prefer to teach them the smart method to learn the particular subject especially on A level biology, A level chemistry and for IGCSE level biology, chemistry, science and combined science. Many smart technique will be using in this online class such as online discussion, online debate, online activity, viva. The students can ask questions according to the given topics and the answers will be given until the understand well.
