Use common sense. If it's something where you are going to be logging into, or a service your using, yes, of course it's possible for them to find out by tracking your IP,, etc.
The question is: will they bother find out? If it's something small, odds are the bank will just refund the money to card holder and not bother.
I am not sure what your plan or motivation is -we're all assuming it's bad, it may just be a poorly worded question-but if it is bad, I am trying to figure out why a kid studying for the ACT would want to take a risk like that. Don't do anything dumb.
