Hi All

I apologize if this post is meant for some other forum here.I find this place best to get some opinions.

This is regarding the Difficulty level of Platinum GMAT free online test. I must admit that i felt that the Quant section was little tough, moreover the questions were not of the type as we see in OG.

Also what surprising is that i did 15 incorrect Questions and still it says the RAW sore is 48-49.

As far as i know ,to get 48-49 , you can only go till 6-7 wrong questions. Here is the Questions wise statistics ( Red coloured are the wrong ones marked by me )

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37.

Do you think that still it is possible to get 48-49 after doing 15 wrong questions??? Please revert guys.

Thanks in advance.

Hi shekhar,

I dont know how close Kaplan scoring algo is to the real GMAT scoring algo.
But in my opinion it is quite possible to get a number of questions wrong and still get a good score.

Last time when I gave the GMATprep 1 test(which is developed by the creators of the REAL thing), i got around 8-9 qs wrong and still got a score of 50 in quant. This more than proves the point.

The information in this link cleared a lot of stuff for me. Check it out

Ya, there's really no reason to put any weight in the scoring algorithms used by third party CAT exam providers in my opinion. GMAC's is the only true CAT. Now, of course, for practice and learning third party CAT exams can be valuable.

With that said, I've also looked at Platinum GMAT's CAT and doubt seriously that it is adaptive at all. And furthermore, I think many of their questions are too computationally intensive in comparison to actual GMAT questions. Actual GMAT quant questions, in my opinion, are just much more elegant in general.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
