I cannot take SAT II U.S. History?

I signed up for 3 subject tests tomorrow, and I’ve made a huge mistake. I have learned that I know nothing about the history of our country, but it’s too late to change reg now.

If I just show up and don’t take it tomorrow, do I automatically get a 200, or do I not get a score report at all? Will colleges see that the score was “cancelled” or something else, and will that hurt me?

Thanks!

Leave after you complete your first two. USH will not be reported.
