in my first attempt, i referred to this book. In my opinion, this book is not sufficient, Sir Naveed bhutto notes are good during exam days for revising when you know the whole story behind one line or one word written in them. However, thy may give you 40 marks if you keep yourself update with new developments and perform well in objective. But for 70+ marks, not at all. This book contains just highlights not details and miss many important points to keep it concise. to best, you may guess from its name, CRAM SERIES, it's same just like in school you prepare just 8 out of 20 questions. Now if luck is with you, 3 out of 5 questions come in paper from those 8 questions and you pass the test, or vice versa.

I hope you got my point.
