Ok - Just a few days before the big day and would like to brush up on the most *Common* idioms... I don't have time to look through several pages and memorize them. Has anyone come across such a list?
Idioms are not being tested on the GMAT anymore. It doesn't mean sentences won't have idioms in them, just that sentence correction questions based upon just incorrect idioms are not tested.
Do some searches on this site and google and you 'll come across official news/reports regarding this.
Hope this helps.
