Hi november22,
Since the GMAT is still the same predictable Test it's always been, the books that you're using are fine (newer versions of those books would offer some new practice materials and advice, but nothing so ground-breaking that you would need to purchase those newer books).
GMAT assassins aren't born, they're made,
