Applying on the last day of the cycle?

hey has anyone applied the day of or the day before the application cycle closes? If so did you write an addendum?

my lsat score comes out tomorrow and I have my letters of recommendations and finishing (thx adhd😍) my personal statement. if my score is a lot higher than I expect I’m just going to say f it and apply. I mean the cycle stays open for a reason and you never know….

so has anyone does this?
