Hi I haven't registered for the GMAT yet, but I plan to. On the site it says I get free software? What exactly are the free prep materials that are provided by mba.com? Do I need to supplement them or will that be enough with the OGMAT book?
The free stuff most people refer to is the GMATPrep tests. Be sure to download this software! It contains the two best GMAT practice tests available, featuring real but retired GMAT questions.
Good luck!
