Hi all - I took the GMAT 6 years ago and it recently expired so I have to take it again before applying to b-school 
It looks like the prep material has changed in all those years. In the past I used Kaplan and Manhattan GMAT prep books. I've also noticed a number of mobile apps like Prep 4 GMAt but don't know how good the content is.
What do you all generally recommend we use now?
