First of all this book is in question answer format , so it's better not to expect a textbook like experience. However the book has very rich content. Usually we don't study seriously in final semester and hence this book is very helpful for 60% preparation in just 5 days or so. PROS:- 1). Very rich content. 2).Good print quality. 3).Helpful in emergency situation.Can score decent marks by just studying 3-4 days. CONS. 1).Not for serious students.The name itself suggests, "Express Learning". 2.It's mainly for preparing examination.Not for hardcore learning.
