do i need an addendum for a cancel? Forum

[wsjch05]

I'm applying to NYU/Columbia with a cancel (october) and 174 (december), with 3.58 gpa

i read that Columbia requires an addendum if there had been a significant jump/drop in the score,

but do i need one for a cancel??

thanks in advance.

I wrote a really short addendum for my cancellation, just in case it is necessary.
