After reading a lot of good reviews I thought of getting my hands on ...so here is my 2 cents on the book so far -
1- Very concise, crisp and to the point guide!
2- Basically a spin-off of Wren and Martin with some tailoring to suit for GMAT! (Just few days back I went over Wren & Martin for jogging my basics so can say this good confidence)
3- Miscellaneous error at the end of the guide is quite useful (and good review material before you take on the test)
4- Idiom part is very comprehensive and backed up by examples.
5- I see many asking whether one should go for this if one has already
MGMAT SC guide- to me it makes a lot of sense to keep both of these (both of these books are in different league- I would start with Aristole SC Grail then move to
MGMAT SC)
Few not so good points about this is- not too many quality practice Q's ( but hey I got many other sources for that, to me it is not an issue at all), I find some examples given with minor mistakes (do not remember exactly the page number but it was regarding use of one-another/each-other and 1-2 more places but all these were easily identifiable one's )
