What if I don't want my ACT score to be sent to my high school?

I’m taking the ACT as a sophomore in order to get into a dual enrollment program. I really don’t think my score will be as high as I plan it to be once I take it as a junior or senior, so I want to avoid it showing up on my transcript. Registering, it says

Choose one of the following:
I have or will earn a GED or other form of high school equivalency.
I am being home schooled.
I am not in high school.
I did not find my school code.

None of these apply to me. Do I just lie?

Well if you don’t look up your school code, I guess the last option may apply to you.

Ask the guidance office to remove it from your transcript.
