Okay yes, it’s another one of these questions, I’m sorry :-/ For one of my ECs, it was a week-long camp that lasted 36 hours, but instead I wrote 6 hours. Also, for a year-long EC, it takes up 7 hours per week but instead I wrote 5 hours per week. I have already submitted all my apps, are these changes big enough to report to the colleges?
Both seem pretty trivial - don’t bother.
I made a similar mistake-- don’t worry about it.
