The first piece you should mention is your score distribution. What were you raw Q and V scores?
The second part - 350 is really low. That's 6th percentile (you did better than only 6% of other folks). Why did you get that score?
Is it something silly and obvious (e.g. took you too long to figure out how to use the system) - you are lucky if that's it since it is easy to fix
or are you really really rusty and long time out of college?
It does not sound as though you have a challenge with English, which is good... i think.
As to improvement, you can count on (average - very average) about 100 points due to
MGMAT books. Another 50-100 if you put good effort in, and another 50 if you drill through every question you get wrong. That's 250.
So that's what you can count on. I hope you did something silly during your gmat prep and you can raise your score quite a bit within days. Otherwise, you are looking at 600 as your ceiling... there are exceptions of people from 450 to 700 but that's rare... very rare.
I hope I did not let you down - I would love to see a turn around story and be proven wrong.
These are just averages - not a reflection of every single person and improvement that they have had.... just averages - absolutely feel free to beat them!!!! and you should!!!
