I had a recommended by a friend titled "how to read better and faster "by norman lewis.the book has really helped me with the gmat reading comprehension and will definitely do so aybody needing requirement.40-45 minutes per day for 30 days will be sufficient to get the hold of the principles and strategies given in the book.
