Alright here we go…
If you went back to your common apps like I have an found any typos/errors, feel free to share…
I personally made 4 mistakes (3 minor spelling typos, not self reporting AP’s) and am just in a mess. Very paranoid/anxious over my future in fact. But I did sent updates to colleges about the more important mistakes. Feel free to share your stress in this thread. I’m all with you! I was initially sick to death about my typos but started to feel better after finding out that those minor, petty typos won’t hurt me too much. May the adcoms be generous to us 
similar situation as well
I wrote it’s instead of its in an essay for Brown. Very nitpicky, I know, but it annoyed me for days!
LOL I like to avoid going back and looking for if I did anything wrong. I spent so much time on it (Was on the websites for weeks on ends, hours on hours, nothing was last minute) that I just want to be confident in that I caught all of my mistakes in the beginning.
I wrote “reigonal” instead of “regional”. I’m not sure if it was an accident or I really didn’t know how to spell it when I was filling out the common app. For some reason, I think my mistake will go unnoticed.
