It is recommended that, to draw the best from this book, the students should regularly attend the teachings in their class-rooms/clinics. They should also study a standard, prescribed textbook.

Each chapter in this book has a few long questions, short notes, and viva-voce questions, duly answered. MCQ type of questions and their answers are also given in each chapter. For complete coverage of the syllabus in a chapter, students are advised to go through all the questions and their answers and not simply one or two type of questions (e.g., only long questions).
