Query: The Caardiothoracic SurgeryResident Pocket Survival guide

This is a good handbook for residents.The text covers a lot of grounds for students who are going to take the exam. But before you buy it, please look at the size carefully, you will find that it is smaller than your ownpalm and very thin: only a few pages. Think, how much could it really covers. It is a con. It does not worth it at this price. It should be a free distribution or something to go with some larger text book you bought.
