UC's want all my SAT scores

So as I was sending my scores I realized that the UC’s want all of my SAT scores. I have took the SAT a total of three times. I got 1810 twice and then a 1950.

Do I have to send all my scores or can I just send my highest?
Are there any repercussions if I only send my highest?
How will they know if I send one or all my scores?

Additional Information:

My SAT score went down from the second to the third time. So it went from a 1920 (sorry typo) to an 1810. Will they view that as a fluke? That I just got lucky but in reality I’m at an 1810.

They take the highest total from 1 sitting so they will use your 1920.

The UCs rule requires all SAT tests if you send any SAT test. It is not an option you can decide to ignore. It will then use for admission that test with the highest composite.

@drusba, don’t they only ask for one score where your total was the highest? They don’t ask for all scores AFAIK. They only want the highest SAT 1 score…
