There is no dearth of competition books for engineering and medical entrance examinations. But there is no single book which completely satisfies the intelligent student. The present book is a serious attempt in this direction. We have left no stone unturned to get â€˜EXTREMELY SATISFACTORYâ€™ grade from the readers of the book. Some salient features of the book are as under : (i) No superfluous question. Only those questions have been included which have either been already set in different examinations or are expected to be set. (ii) Most systematic presentation. It is the only book in the market which has systematically categorised the study material of each unit.
