Princeton tests are proprietory material and are copyrighted. You would need to procure them from the publishers. Power Prep tests are old GMAT tests. They are also sold by GMAC at mba.com. However you have the GMAT prep tests (that is similar to the actual GMAT) available at mba.com for free.

Thank you very much Prasanna.
Do you think it will be enough if I study on my own practicing with the full tests and getting the detailed reports on my weaknesses (I'm thinking about the MGMAT reports)? Or will a private tutor be more efficient to help me to work on my strategy? Many thx.

If I were you, I would take a test to see where I stand. I would evaluate my performance in light of the required score and assess my weaknesses. I think this would help you answer the question. If you need private tutoring and have the time and resources, there is nothing wrong in using it. But first determine what you need. You may be able to manage with self prep too.

I think the OP means the free one that is on Princeton Review's Web site. They do give you a freebie online if you do the online course demo. That, you can find at https://www.princetonreview.com/mba/test ... GMAT-TOOLS

I believe they save your results on the site. I took the Cracking the GMAT tests that come with the book/DVD, and they save your results and they break it down by question type so you can identify weak areas. I would start with something like that before considering a tutor.
