Community College- 3 years???

I graduated from high school (tested out) when I was 15 and enrolled in community college as a psych major. Now I’m 16, it’s my second year, and I have since changed my major to biology and plan to go to medical school.
Originally, I planned to transfer to a UC for psychology which would have only taken me two years, comfortably.
Now that I’ve changed majors, it will end up being three years at community college before transfer. I’m not excited about it at all. Although I do love my school significantly more than high school, I’ve always been the type heading for Stanford or an Ivy League, and going to a community college at all was hard for my brain to get past, let alone going for 3 years.

Few questions:

  1. Is transfer (to a UC or private university) going to be more difficult because I took 3 years?
  2. If I go to a UC, finish my BS in biology, then apply to medical school, will the medical school look back and be unhappy with me going to community college for so long? What type of medical school would I even be able to apply to? (I mean are the Ivy Leagues totally out of the question, even if my application is otherwise enough?)
  3. I took a big risk switching to biology for several reasons, including that I have a 4.0 GPA so far but have taken very few hard science classes, and that I was entirely confident that I could transfer to a good school in two years for psych, but I’m not so certain I will be accepted to a good school for bio (because I don’t know how well I’ll do with the science coursework).
    Should I apply this semester (for fall 2017) to some UCs and private universities for psychology, just so I have the option? Because I’d hate to skip applications for next fall (which will be two years from when I started) since I’m planning on doing biology, but then decide I don’t want to stick with biology, and be stuck at the CC for 3 years for no good reason.

Thanks! (Man that was a long post!)
