Initial lesson would involve me figuring out where your strengths & weaknesses lie in Maths and/or Physics, which would just require an easy-going discussion about the subject. After figuring this out, we would then move to working on the weaker topics within the subject, through theoretical explanations, worked examples and then finally (and most importantly!!) past paper questions. This process can be repeated for the other topics, whether they're stronger or weaker. This is a method that I have found works extremely efficiently and effectively to develop a deep understanding of the topic and an ability to solve questions with your eyes closed :)
