Depending on the schools that you apply to. Some have spring admissions, which means you might be able to start as early as Feburary but most of them start in the fall, around September. Good luck!
OK, thanks. So let's say September, I still have time to prepare. But could you suggest me a timeline by which I should finish my test(GMAT&TOFEL)? Because I know this is a long way to apply after your test, but I am not sure how long it is. Thanks in advance.
