About sending GRE scores to university

What if the Universities that I sent the score don’t accept me or I choose to go to different university.
Since I am not sure of what score I am going to get. Should I send the scores anyways or should I keep it quiet if I get a bad score. And try to take the test again. Is there any penalties to take the test again if I send my scores?

Hi, you can choose to send them in later for a fee if you like, right?

Yeah, but I wanna take advantage of the 4 free university option.

It’s your personal choice, right?
