Any of those providers are fine.  I've used Simplilearn's online class for the PMI-ACP exam I'm preparing for and was satisfied with it.

In my opinion, those classes are really meant to be used to compliment rigorous self study and to fulfill the 35 hours of classroom study required by PMI.  I've heard some of the expensive boot camps can help some people pass without the necessary study by using an intensive 5 day, 8 hour a day cram and jam of facts that you'll most likely forget after barely passing the exam.  I really don't like this approach because I think it diminishes the value of the PMP which is to validate your years of PM experience and knowledge.

But if your in a hurry and have funds (which may be provided by your employer), then try one of the boot camps many of which guarantee your success or your money back (or take the prep again at no cost).

I have some detailed resouces on my site that may help you:

 Hi Jeff,

Sorry to hear that you failed.

I am not yet a PMP (in the process of), so not sure if you will value my words. I will suggest go for PMTI or PMstudy. both are good.

Currently I am doing the online test series from PMstudy. and will join PMstudy classroom training. 

All the best for your 2nd attempt.

 Hello Jeff and others,

PMstudy has experienced and fully committed instructors.  All of us continually collaborate to make sure we're providing the best anologies, teaching methodologies and exam tips to ensure our participants have what they need to come into the exam with confidence and wisdom to succeed. 

For you, it's possible you went into the exam having memorized the information but could have lacked the comprehension to move from knowing the material to applying the tools and process to favor a successful project. 

Remember PMI has worked very hard to provide Project Managers with the necessary tools and processes to ensure project success.  They are truly proud of their work and walking in with that respect will support your aspiration of passing.  Our PMstudy instructors make sure you know the why.  Why is the process useful? Why should the tool be used and used in this process?  What is the negative outcome should you choose to forgo a particular tool?

Also, our instructors become your partner to passing.  We're availabe before, during and after the class to help you succeed.  I'm not sure other providers go to this level of customer service but we do.  That's the real value you're looking for, and PMstudy provides that value.

Regards, 

Scotty

Hi Jeff, as a PMstudy instructor, I can tell you that you should seek a provider that will cut to the chase and provide you the information you need to pass the exam.  Here at PMstudy, we take the advancement of our students seriously.  Each instructor has taken the PMP exam, therefore, we have personally experienced the "pain" of preparing for the coveted PMP credential.  Our instructors come from a variety of industries and have the ability to bring "real-world" experiences to the classroom.  You are already a project manager - no one can take that from you.  However, our classes are designed to take what you do every day at work and link your daily project management experience to PMI's terminology and best practices.  The end result is seeing PASS on that exam screen after you hit the submit button.  For more information, visit our website www.PMstudy.com for upcoming classes in your area.

This app allows you to kill any spare time going through PMP terms. Really helpful for clearing the exams. I found it very interesting.

 Hi Jeff,

Have  you joined PMstudy? Or any other provider?

I will be joining soon. Plz let me know if you are willing to join PMstudy.. then may be we can join together....

It seems they have some referral scheme may be we can use it :). What you say let me know.

 I see that you are going with PMStudy. I am not affiliated with anyone, but did use Simplilearn, PMStudy and PM-exam-simulator for mock tests. I did not take any of the courses - just studied PMBOK once and Rita 6th edition twice. Did pass my exam today (will post LL in a seperate post). You might want to be careful with the mocks that you use. During my preparation, I did notice that a lot of material out there on the web is extremely low quality.

I am very impressed with pm-exam-simulator. They have a free section, where you can literally test drive their system. I think it allows 10 questions in each Process Group plus 3 quizes with 30 questions each (the quizes do take some questions from the packets of 10 questions that were used for each process groups). I did not buy their paid package. 

Good Luck.
