Should I not send in my sat subject test scores?

So I took three subject tests in one day (studied very little to be honest) just to see which I would be good at. Long story short, I was bad at all three:

US History: 570
Biology: 520
Math 2: 600

I know these are really bad, I’m not a genius like most people on college confidential (LOL). I ended up retaking math 2 and got a 720 so I am sending that, but i’m leaning on not sending my other 2 scores. I’m applying to UC schools so they don’t require any subject tests to begin with. Should I send my 570 and/or 520? My counselor says yes but I have a friend who went to Berkeley that never sent her scores because she wasn’t satisfied with them either.

Thanks in advance.
