is there a way to get the sketch from my arduino uno to my computer?

hi, I recently found out my school had an arduino uno r3 with a motor shield attached to it. it has two dc motors and a sensor on it(but that's not really important). the sketch for it is no where to be found on the school computers. when I plug it in, it starts to drive around so there is definitely a sketch uploaded to the uno. is there a way I can get the sketch off the uno and on to my PC?

It is NOT possible to get the C-code. It [u]may[/u] at the best be possible to extract the machine code and, with a disassembler, get the assembly code. (which wont help U much).. sorry for yor loss.

well thanks anyway, you probably saved me a lot of hours of searching for a way to do that.
