It may be the case that you're already scoring above your target score, in which case you may not need to prepare at all. Or it may be the case that your current plans are unrealistic.
Brent - Greenlight GRE
I m planning to appear for GMAT but won't be able to attend any coaching classes due to my job profile which involves lots of travelling. Somebody please guide me whether it is feasible to prepare for GMAT without any formal coaching. Also please let me know if there is any online coaching available for GMAT.
