Hi, i want to ask about GRE. I am thinking to apply to US uni but most of them want you to take GRE tests.I would like to ask if anyone knows how difficult it is.I already have a MSc in Politics from the UK,how difficult is to achieve high scores? What's considered as "high scores"? I would also like to know how long does it take to study.I am starting my military service in the next weeks and it's going to last until May 2011. I am thinking applying next winter.When should i start studing for GRE??? Also I am not a native english speaker but before studing for my MSc in Britain,I achieved 7.5 in IELTS with only a month studing.

Thanks again for any answers understand that everyone is really pressed.
