First of all, I make sure that a student has understood the basics of the chapter being discussed and also all the types of calculation needed to solve the chapter. After that, I start from the simplest type possible question related to the chapter. I gradually increase the difficulty level and also change the type of question. Before assigning practice questions to the students I also make sure that all types of questions have been discussed. I collect the questions from different sources and explain the simplest method to my students. I never give ready made Formulas and shortcuts because I believe in the fact that, only practise and crystal clear concepts can make you a good student.
