We have tried our level best to make this book easy and thereby exceptional. Students will be able to get basic knowledge about Defence Services exam and othe related exams. We have put much emphasis to develop the book and make it accurate and exceptional to the examinees. We have discussed detailed information regarding how to participate in the exam, how to collect application form, where the exam centre is etc. Moreover, exam procedure, activites after passing the exam etc. have been elaborately discussed. Despite our endeavours, there may be slight errors. Hence, we request the teachers and students to remit those errors. Any good suggestion to develop the book will be most welcome. Finally, we think and believe that our labour will be fruitful if the book brings any benifit to the students concerned. Yours faithfully, Firoz Ahmed
