i agree with most of what you've said, but not necessarily with the following:
dhoomketu Wrote:-Questions in GMAT focus are of same difficulty and style as OG11, which is what everyone is looking for.
in what i've seen of gmat focus, the 'style' (as in focus and content area, not writing style) has, at times, diverged markedly from that of the official guide questions.
for instance:
(in general enough terms not to be violating copyright - please don't ask for specifics, thank you)
* gmat focus features data sufficiency questions whose answer is 'DEFINITIVE NO': i.e., a 'no' answer that is Sufficient.
the fact that 'no' and 'yes' are both SUFFICIENT is probably not news to anyone who reads this board, but, surprisingly, neither og11 nor the green quant supplement contains a SINGLE QUESTION to which the answer is 'definitive no = sufficient'.
we at mgmat were therefore in doubt as to whether the gmat even considered 'definitive no' to be sufficient at all, but gmat focus has settled that question in the affirmative.
* while it's true that many gmat focus questions simply follow in the footsteps of og11, there are some questions featuring innovative and unusual new approaches to old topics (especially in probability and statistics).
overall, i think that you should check out gmat focus as a possible bellwether of current and future changes to the topics emphasized by the test - _IF_ you have already completed an exhaustive study of the problems in the og11 and quant supplement. if you haven't, then your time (and money - gmatfocus isn't cheap) would be much better spent there first.
