RED FLAG OPTOMETRY SCHOOl

Hi,
I am applying for this cycle for optometry schools and I was wondering what are the red flag schools I should avoid big time and also why are the red flag?

Q2: what are the things I should consider before committing to a school??

Q3: I have a 3.0 and I have not took OAT yet but if i get into a school which is a red flag should I just go with it or waste a year and apply next year in the beginning of the cycle to probably score a better school? I am 25 BTW and a girl so my parents are desperate to get me married.

Q4: My parents never went to school and I am the first born so whatever you think I know i probably don't know so any advice is appreciated.
