Having Difficulty Finding Classes to Fit My Schedule

Hi everyone. I am 29 and looking to start my premedical journey. I have considered being a physician for approximately 10 years, and I finally decided to start working toward that goal. I have a background in healthcare finance and will be working full-time while attempting to take the prerequisites. I am concerned because none of the programs in my city offer night or weekend classes. I thought about taking some of the classes online through either the University of New England or Doane University online. However, I know that it is frowned upon to take courses online. I thought about working part-time and taking premedical courses, but that would result in financial struggles. I am unable to take out any undergraduate loans to finance my education. What do you all recommend? Any advice is appreciated. Thank you in advance.
