I may be a new member on this forum, but I am not stupid, which is what your post seemed to imply...
I do not know exactly how many questions the PP has because I've never taken the GMAT before, and I've never downloaded the software. However, if the current software is composed of questions from edition 10, and the two supplemental texts that are being released have questions that are all found in edition 10, it is my personal opinion that there would be quite a bit of overlap between the PP, the supplemental texts, and edition 10. That is why although the article said most of the questions in edition 11 have not appeared in previous editions, I noted that there are 3 different sources pulling questions from the 10th edition, and that buying the 10th edition could be redundant. I'm assuming the material in the supplemental texts could add more insight than the material in the 10th edition that I am hypothesizing could be the basis for edition 11.
Though your post brings out valid points, I believe you could have responded in a much more constructive way than to call me ignorant and my post ridiculous. I understand that people work very hard to get a 700+ score. That being said, someone trying to get an MBA should be able to think for themselves and know that posts on this forum are suggestions and helpful tips that are usually rooted in the personal opinion of the person who is writing the message. I did not post any false information, I merely posted an article and gave my interpretation of what it meant and how I was going to handle my preparation for taking the test.
I did not tell anyone that my way is the only path to success. I gave a suggestion. I believe in this forum, as I know many people have taken advantage of its members' experiences to achieve their goals. I sincerely hope no one else shares your sentiment.
Finally, and above all, I believe in treating others on this forum with respect and decency.
