📌The contents of the book are aimed at the students of intermediate level. Each chapter is a complete lesson. Important issues have been emphasized and sometimes repeated, to ensure a complete and competent understanding. Every lesson is followed by a list of questions to aid comprehension. This book without a doubt is not free from error and mistake and I hope that with the help and advice of teachers, these errors and mistakes will be corrected in future editions.
