All AP classes but I got bad grades

My Background:
I was raised by my relatives and I had a hard time accepting my parents after i moved to america. And due to culture shock, bullying at school and mental abuse from parents, i stopped trying. I suffered from depression and probably ADD and I just gave up on life and didn’t show interest towards anything. I tried to end my life several times but thankfully nobody knows about it. I don’t know what i was thinking but i was never able to get proper help from an adult.
Essay: Im thinking about writing about how a loved one died because of inattentiveness of the doctor and how the death shaped my life.

Columbia doesn’t have a Common Data Set to check requirements for transfer applicants, but I imagine they require

  • High school transcript
  • College transcript(s)
  • Essay or personal statement
  • Standardized test scores

Columbia will need to weigh and reconcile your uninspiring high school career with your stellar college one. You need to convince Admissions that you are more deserving of a slot than another applicant who was Ms. Polly Perfect in high school and at their current college. You do that by identifying what Columbia can offer them that cannot be found at another college. And then you pray!
