I think the Economist Scoring is weird...
Today I gave free test of The Economist GMAT Tutor, - q49/v30 - 640
Q 49 - even after 16 wrong ; 2 times 4 continues questions wrong. (GMAT PREP - 11 wrong - Q49)
where as in Verbal ,
Only V30 - after having just 10 incorrect that too not consecutive.
Incorrect Q.s - 1,6,13,17,19,23,24,29,35,38.
I have never got less than V34 in
MGMAT , and my number of incorrect questions in
MGMAT CATs were between 15 to 18 , in fact I got V36 and V38 in GMAT PREP.
Also , questions were too easy to answer in Verbal. I was surprised to see
V30. !!!!SC - Almost all SC were one liner questions.(which is not the case in REAL GMAT).
RC - Too direct questions, NO Inference based.
Quant Q.s were time taking, good for practice. But Don't Rely on the scoring.
