UC TAG + Personal Insight Questions help?

I’m kind of on the verge of several anxiety attacks trying to figure out what to do. I know my transfer counselor is probably tired of seeing my face, bless his heart, so I’m going to try to ask my questions here because I try not to disturb him on Saturdays.
I ended up failing my Calculus class the first time, retook it and got a B for summer (which is when I intended to take my second English composition class). However, I seem to have ruined TAG for myself with that irresponsibility. I only have 29 units (but I heard that this might be okay?), can’t apply for TAG at UCD, my first choice, because I only have one English comp class, and can’t apply for TAG at UCI, my second choice, because my GPA is now at a 3.3 and they want a 3.4 at the end of Summer 2019. I really didn’t have any other schools on my mind for TAG so I need some advice on which school would probably be best for me to use for my TAG?
I’m a Psychology (BA) major and I think I’d like to double major in something a bit more science focused as I also want to go to med school (please ignore my sub-par GPA, I’m working on it, I swear), but psychology is what I’m most passionate about . 3.31 GPA, Sophomore, I volunteer at a hospital, I’m also heavily involved in the African American society at my school and I’m planning to join the pre-med club and an honor society this year.

Second issue, I’m not sure what to write about for my personal insight questions. I’ve narrowed it down to this:

  • I graduated from high school at 16. I skipped two grades. (I would use this for the significant challenge question, the significant educational opportunity question, or the question about what makes me stand out)
  • I immigrated to the US with my parents from Nigeria when I was 5. But I feel this is a common topic to write about and there are a lot of immigrants writing about this. (This would be used for the significant challenge question)
  • I went back to Nigeria after 9th grade to complete my high school education. (Significant educational opportunity question)
  • I’m very intuitive, to the point most people in my life think I’m psychic. (For the talent or skill essay)
    I’m a fairly good writer and have good ideas for each of these, I just need to know which ones would be most unique or better executed?
    Thank you sooo much to anyone who can help out!

You need 30 semester units by Sept to TAG any UC.

Alright that’s fine, could I please get some help with the insight questions then if possible?

maybe choose the prompts most people stay away from like #7 “Beyond what has already been shared in your application, what do you believe makes you stand out as a strong candidate for admissions to the University of California?”
and I agree about the immigrant story because I am considering writing a similar topic based essay this time. my advice would be to show how that has changed your views on life and helped you grow not how it has been an educational barrier
