That's very unlikely. She is currently #616 and it seems she won't play any tournament before late October or even November. By that time, she will be able to play only some 10k's or 25k's at best, and so far she has never got consistent enough results to climb the rankings that fast.
If she does well, I think she can reach the top 500 by the end of the year but not more (unless she does VERY well, and I hope so too!).
I so sorry I thought she was rank around 400 my bad but yeah top 500 would be good ended ranking for season, I seen a couple video on youtube with her playing and follow her junior result she seem very talented but like you said she need too get more consistent I hope that time will come soon as well

Zuza finished as 4th in Angie Cup (pro series of Polish Tennis Association). Beat easily players in her group. In the final group she lost to Shoshyna and Lewandowska, then withdrew from the match with Przybylska.
I don't think so, it's probably more something like a lack of funds.
She has launched a website earlier this year: http://zuzamaciejewska.pl/, where she speaks essentially about tennis. That being said, there has been no news since mid-July.
