With knowledge comes questions and by questioning comes answers. Therefore, constant thirst for better ways of presenting a given matter led us to the discovery of this book which would not have come true without the earnest efforts of all our teachers and colleagues. Exams always instill fear in the minds of students and in spite of this, students are expected to perform the best. But many a time even a hard working student may lose marks due to lack of proper presentation skills.  Well! The efforts made by us for our exams, we thought, should be made available and useful to everyone. Yep! We believe in the saying “Give the best you have and the best will always come back to you”.
