<p>I had a SAT Subject test on June.
I should pay SAT Change Fee today.
But, there is a problem.
I have a debate concert today and I'll be in tomorrow.
Moreover, my score is very lower than I expected(I got a good score in model test)
If I wouldn't pay SAT Change Fee, SAT score would be cancelled privious one and this score?
and is there any bad effects on my later score?</p>
