You should run the NPC for Smith College, and share the results with your parents. You will need their help. If you google “Net Price Calculator Smith College” you will find it.
I think that your chances for admissions at Smith are relatively decent. However, with a 36% acceptance rate I do not think that it is a safety for anyone. Also, I have no idea whether you will find it affordable.
You have both rather small colleges and relatively large universities on your list. Do you know which you would prefer?
I think that you are a very strong candidate at quite a wide range of universities and colleges. However it is hard to know what to suggest since it is not clear to me what you want in a university.
Do you have some sense regarding likely major(s)?
In terms of improving your chances, I think that you are already doing very well. Keep doing well in your classes, participate in the ECs that are interesting to you, and treat people fairly. Continue to keep ahead in your class work. I think you are already doing all of this and doing it very well.
I do wonder if you should do some ACT or SAT preparation and retake this.
