My Experience (in short):
Like i said earlier: The GMAT was on the 20th.
The Centre:
1) You cannot take in anything. period
2) no vending machines wud be available. but one water dispenser can be found. i took my diet pet bottles.
3) breaks are 10 mins each - one after AWA and other after Quant
4) formalities aren't much but everyone is taken in one at a time so time wud be spent in allotting lockers and assigning seats. i wud say be there by 8:30 if your time is 9:00
5) no unnecessary signing as was with ETS. only 1 digital signature with a biometric set-up (fingerprinting and digital snap)
The Start:
No codes etc are required for universities. just the names wud do. the search fucntion from Pearson even allows for search for abbreviations like MIT.
The Xam:
my AWA topics were
Issue: on whether business leaders have more opportunity to change the course of opinion of a community or even nation
Argument: effectiveness of a newspaper's advertising.
i must add that the two were tricky. havent seen the entire list so cant comment on a relative basis
Quant: Few Surprised here
Stats (median/mode etc.) : No question in the entire paper!
DS: tougher than ETS. for sure. no doubts about it
Word Problems: about the same level
ProbabilityP&C : i think i got only 1 question over here too
English: Much different from ETS
Bold-Face: The bold face was a gud one. I wud not recommend Scoretop for ppl preparing for Bold faces. for one their examples are much tougher and also because i did not agree often with their choices. (i got only one)
Critical Reasoning: tougher than ETS, i think. but not by much
Sentence Correction: much clearer than ETS and therefore easier to tackle with. although everything has exceptions. but on the whole i wud say easier
RC: I got 5 passages (Yes i did

)
2 of about 65 lines
2 of about 45 lines
1 of about 90 lines
as were expected. so i wud say not much different from ETS.
On the basis of the above i wud say that GMAT has changed ever since Pearson took over. maths was in general tougher. english was more or less of the same level. not easier as some might say.
