in a bad place by not doing it?
If you mean the “additional personal information”, probably not. You might have missed a vital chance to strengthen your application, but this is one of the few cases in which an “optional question” is actually option.
I did the additional personal information, but not the research, because none of my extracurriculars include researches. That wasn’t my direction.
I didn’t do the additional identity question as I thought I covered everything related to my background in my other supplements. I wouldn’t worry too much about it if you covered some aspect of your background in your other essays.
No, as there was nothing more to add. Highly doubt it affects decision.
Nah not really doesnt matter
