Applied for Financial Aid?: Yes
Intended Major: Business Administration/Management, Marketing, or International Affairs
State: CA
School Type: public school
Ethnicity: Asian
Gender: F
Income Bracket: a bit below average, I think (single parent household)
Family background: Dad doesn’t have education past middle school, mom went to SDSU and had to drop out and work due to financial circumstances. Rest of my family went to community and dropped out for similar reasons.
I have… interesting (unique-ish)… familial circumstances that I don’t want to go into detail here.

Schools I intend on applying:
NYU (my top choice, for Stern, hopefully Class of 2021)
Columbia (I know I’ll get rejected)

I don’t really know any colleges that fit my credentials, so suggestions would be really appreciated. I know I have pretty good letters of recommendation for teachers. My main concern is how math will affect my admissions chances/ anything I can do to improve that for NYU, beyond retaking Calc (I’ve emailed the admissions officer with the same concern, albeit providing less information.

^^ Oh, would like to add that I’d really appreciate any SAFETY/MATCH college recommendations for Business and International Affairs as you can see that I haven’t looked at many. Thank you!
