Question! My future

Hi
How is everyone! I’m enjoying NBA playoffs! Go Heat!!!
Question, I currently go to School of Visual Arts in NYC Computer Art major.
Next year, I’ll have to choose either Maya or Flash. I have a little background in Flash(actionscript a little bit) but my knowledge of it has flown away since I haven’t done any Flash for a while due to schoolworks.
Question is should I still learn Flash(like actionscript stuff?) when I study Maya?
How much is it necessary to know Flash and if so how much of Flash should I know?
Of course, I will learn anything that I can get my hands on but I’ll dedicate most of my time to Maya. I just wanted to know how much knowledge of Flash and other software should I have to actually be succesful out there?

Thank you!!!
