Well,
I wrote to manhattangmat and asked them to how they generate their scores. I haven't received an answer yet.
The're two points that fetched my interest:
1. The score range to which they relate a question
2. the total score including percentages
2. How they create the percentile? Don't know, but I guess they simply use their data obtained from testtakers on their site.
But maybe they relate their "raw scores" to those of real gmat tests.
1. After I've taken the test I wondered that there were very few 700-800 questions in each of the sections. Most probably the online test isn't adaptive, but we should evaluate that. I had a score of 700 with 42 in math - there were just 5 "700-800 questions" (got them, but made six slips of the pen in others)- and 46 in verbal with 6 "700-800"er.
Sperumba what was your score in exam 1; how many "700-800 questions" have you received in quant and verbal and what were your scores respectively?
In my opinion the quant section is far less tricky than that of gmatprep ( the hard questions), but more difficult in respect of the tested concepts; you must use your math knowledge more flexible.
The questions are less difficult than those of the challenges at gmatclub.
I don't know Kaplan anymore, I've decided to sell the 800er because I didn't find worth it, so I can't compare them.
Verbal is less difficult than verbal of gmatprep; while manhattangmat SC's have some interesting aspects and are sometimes tricky they are quite different, create less pressure.
The RC's and CR's aren't difficult, as far as I can see. Well have just taken one test.
However one should only compare the real GMAT with those tests generated by others, not those of others among each other.
Sperumba, and others, please share your repective scores as well as the number of 700-800er questions you got on the manhattangmat-online exams.
Thanks
