Probably a bad sign that i keep finding mistakes in my app.
I noticed some of the hours on my common app didn’t match the hours in my resume :l ( i put fewer hours on common app)
In mid-november can we send a new resume or is that not allowed?
No, just leave it as it is. It’s not a glaring mistake and at this point, it’s not going to matter much. It won’t make or break your application IMO.
