"Head First C# is a great guide to get you up and running with the language as fast as possible."
--Michael James Williams, Activetuts+

"An excellent tool for the hobbyist and professional programmer to learn the language and powerful programming environment afforded by C# and .NET. "
--Ira Laefsky,

"...the content of Head First C# is solid and entertaining."
--Mike Riley, Dr. Dobb's CodeTalk

" exciting, interesting presentation assuring a much higher level of PMP exam 'passes'. Highly recommended!"
--James A. Cox, California Bookwatch: The Computer Shelf

"Here is the best guide we have seen for preparing for the Project Management Professional (PMP) exam. Through the use of plentiful graphics and clever layout (a hallmark of the Head First series), the reader is more likely to be motivated to read the weighty tome, and to retain the considerable content. "
--Michael L. Kleper, The Kleper Report on Digital Publishing

"...a 'must' with contributions from a range of successful team leaders."
--Diane Donovan, The Bookwatch: The Business Shelf

"I needed some solid PM principles to apply to my work in an Agile development environment. So, with a desire to study ole skool Project Management in an Agile way I was drawn to the "Head First" books. And wow! What a fantastic way to learn! Knowing full well that PM concepts are not the most exciting topics, this book grabs your attention by drawing you in with its conversational tone...It's like getting your older brother's school textbook after he's highlighted all the important points and written the exam questions in the margins...literally! Now I'm spoiled, "Head First" is the only way to learn. "
--Christopher N. Scheevel "Neville",

"A highly interactive approach for the complete beginner."
--Mike James, I Programmer

"I would recommend reading this book if you interest in PMP or prepare for the PMP certification exam, it is one of the most interesting books that you can have in this track."
--Rafiq Elmansy, Graphic Mania

"The introduction to this particular book discusses how the series attempts to present the concepts and technical material in a way that is far more intellectually compelling and memorable than the approach currently taken by most books...Although the book will be of most value to newer programmers, experienced C# programmers will find topics of interest and perhaps even some language details and analysis that they have never previously encountered."
--Michael J. Ross, Web Developer, with Greg Hanson,

"I found Head First PMP to be an outstanding resource for teaching project management in a software development environment. Anyone who works in any level of that industry should read this book."
--Jem Matzan, The Jem Report: Your source for technology news

"The authors succintly get to the heart of the matter about why projects fail and what you can do to help reduce the chances of project failure and to help prevent your boss from being part of the problem."
--Richard Kuper, Editor, The KUPER Report

"Even experienced project managers are likely to learn a thing or two from Head First PMP that can be applied on the job immediately. In fact, I personally have restructured my project management plan to more closely follow the PMBOK recommendations (now that I really understand them)....because I read Head First PMP, I feel I’ll be able to better absorb the content in the dull, dry books I’m likely to pick up before taking the exam itself."
--Amanda Johnson, realeyes media

"This guide helps readers prepare for the Project Management Professional (PMP) exam not through practice questions but through visually instructive illustrated outlines and diagrams, conversational and humorous text, and unconventional activities (i.e. crossword puzzles) which, assert the authors, are not voluntary."
--Shannon Hendrickson, Reference & Research Book News

"Being able to look up what the exam covers is useful information for me, and the book is perfectly adequate for that...I read Head First PMP in its entirity, and I did the majority of the exercises. I'm pretty certain that if I read it again and did all the exercises, I'd pass the exam. I also learned some useful stuff about project management, as well as about the PMP exam. I'd recommend Head First PMP to people who're interested in the PMP exam."
--Elizabeth Zwicky, ;LOGIN:

"Head First PMP is by far the best PMP Exam Preparation book of all I have reviewed in depth. It is the very best basic education and training book that I have read."
--Dennis Bolles, PMP, Project Manager for the PMBOK Guide 3rd ed. Leadership Team, DLB Associates, LLC and co-author of The Power of Enterprise-Wide Project Management

"I just passed my PMP exam yesterday and wanted to personally thank you for writing such a great book. I loved the style, humor and approach - you really made the PMBOK memorable. As an author myself, I'm aware that the best thing I can do is to share my positive experience with others - and have done so in a very favorable Amazon review. Thanks again for your work and for helping me get through a difficult exam with flying colors."
--Thomas Eck, PMP

"Head First PMP by Jennifer Greene and Andrew Stellman offers complete coverage of the PMBOK Guide principles in a way that's engaging, not tedious...The book helps readers prepare for the PMP certification exam with a unique method that goes beyond answers to specific questions, leading them to think about the big picture of project management. By putting project management concepts into context, readers can understand, remember, and apply them — not just on the exam, but also on the job."
--Aaron Smith, Projects@Work

"O'Reilly published one of the most intriguing books in their interesting series "Head First", called Head First PMP by Andrew Stellman, Jennifer Greene. This book is primarily targeting every PM professional that wants to pass PMP exam, but in the way that he wants to understand the subject matter not just to prepare for the exam. Book is easy to read (and you will be motivated to do it properly if you start with almost 20 pages of manual how to use and read the book, which I highly recommend) and it is very interactive which keeps reader awake and in state of thinking, rather than passive reading. I highly recommend this book to every PM professional as well as to those people that are stepping into PM era (no matter if there are PM's or they are part of the team)!"
--Tom Bronzin,

"If you have any inkling about going into Project Management as a profession (PMPing and not Pimping), I highly recommend taking this path using this book to help master the process."
--Robert Pritchett, MacCompanion
