I will first make sure you understand the topic by asking you what your weaknesses are in it and if you feel fully confident then taking a small test and asking a series of questions.I like to use cgp books but iam open to any as long as they are your exam boards.If you are weak in anything I will explain it to you by drawing diagrams and explaining every stage of every process until you understand it.then we will do a series of exam questions together and you will keep a record of them then when I feel you are confident and able enough then I will leave you to it yourself and we will review you answers together. We will go over any part of the topic you were struggling for in the exam questions then we will re do exam questions in that topic.After understanding the topic the only way to get the top grades is EXAM QUESTIONS, EXAM QUESTIONS , EXAM QUESTIONS. There is no escaping this if you want the top 7,8 or 9 gcse grades. In fact even to get a 6 aswell.
