To start, you should plan to budget for a full 8 years of university, where the last 4 are going to be quite expensive.
By the time that you get to medical school is could very well cost $100,000 dollars per year. If we figure four years of this, plus four years of undergrad at a private university (perhaps $85,000 per year) then we are talking about a total cost of at least $740,000 over 8 years. Can you do this with no debt at all? (I will assume the answer is yes and drop the issue unless I hear otherwise).
Some public facing experience is valuable for someone who wants to go into medicine.
Again these are very good ECs for someone interested in medicine.
The first thing to think about is safeties. Texas A&M has a very good medical school. It would be very solid school for you to attend as a premed student. If you are sure that you will get in and if you are sure about getting your intended major then it would be a very good choice. UT Austin is also a very good school. Given how good these schools are, I am okay with the rest of your list being reaches as long as you are confident of getting your intended major at your safeties. If not, I would add another safety.
It is not obvious to me what the out of state public schools on your list have that you would not get at the two Texas public universities on your list.
I think that this is worth commenting on. My wife and both daughters all had majors that overlapped with premed requirements. As one example, all three of them took organic chemistry in university. My wife says that it was tough and the only C that she ever had in her life. My older daughter said that it was the toughest B- that she ever had in her life. My younger daughter waited until junior year of university to take it. At that point she was very well prepared, had done well in the prerequisites, and said “what’s the big deal” and “organic chemicals fit together in ways that make logical sense”. We occasionally see posts on CC from students who are freshmen in university, are taking organic chemistry, and are suffering. They worry about what this will do to their chances of getting accepted to medical school.
My point is that you will be a stronger student as a junior or senior in university than you are now, or than you will be as a freshman in university. You will find some premed classes in university that are tougher than anything that you have seen up to now. You do not need to rush ahead. Instead plan to take the required premed classes over the full four years of your undergraduate studies. For now, just take classes that make sense for you.
As such, I do not think that you need to rush to take more AP classes in high school. However, if you take honors organic chemistry next year, I would not rush to take organic chemistry again in university. Instead I would pace out the university classes, and plan to take the most difficult ones when you are solidly ready.
In terms of applying to some Ivy’s, or Johns Hopkins, I think that this depends upon what you want to do. The top schools get a higher percentage of their undergrads into medical school, but quite a bit of this, some might say all of this, comes from the level of student who gets accepted to the top ranked universities in the first place. Someone who is capable of getting accepted to Harvard out of high school is likely to have the work ethic, study skills, brains, and whatever else it takes to have a good chance to get into medical school regardless of whether they actually attend Harvard or their in-state public universities.
Up to now I think that you are doing very well. I think that you can get a very good premed preparation at any university on your list, or any one of at least 100 other universities in the US.
And I have wondered whether you should consider adding Rice or maybe Baylor to the list.
