For the Cambridge IGCSE, I use Sue Additional Mathematics as the main coursebook. I explain the theories, and guide the students through steps by step so that they will understand the questions, and able to solve the problems by themselves. I tried to make my students getting confident and improve self study skills in the future. I also use past papers to make them familiar with exam questions, and marking schemes. It is a year and a half long process if you go from the start. But if the students want to just to focus on a chapter, it would be around 1 month give or take according to students' own pace.

For the Italy University Entrance Exams, the teaching methods are the same, but only 2 months will be needed to cover for all topics.
