[quote]I think about some affordable distance learning program. But If I got discount of at least 50% - I would go for full-time or part-time. Someone on this forum said that with good GMAT many schools would like to take you on board and probably, even help with founding.
How does that works? I spend 3 mounts (f.e. 200 hours) preparing for GMAT, take a better score and if this score is very high - I apply to better school, and ask them for discount. Does it work like that?
Are there any suggestion of how much time can you spend on GMAT courses until you reach close to your max performance? For example, if I spend 200 hours, will I be close to my max possible?[/quote]

Most likely, you don't *ask* for a discount but receive a notification (ususally shortly after the admission e-Mail) that you get a grant of X USD/EUR. You might want to negotiate but better schools won't be willing to negotiate anything beyond that.

Schools that give you such a substantial discount (50% or more) will most likely be lower ranked and need to 'buy' your GMAT score for statistics purposes.

That said, better schools will also give grants, but they look at your entire profile in which the GMAT is just one piece of the puzzle. Hence, a stellar GMAT alone will not give you $$$ at a top School (most likely not even admission).
