Re: an above comment, all the Ivies “meet full need,” based on their own formulas. You can also Google for a list of other schools which do.
For the Ivies and Stanford, plus the highly competitive others, first and foremost, you have to understand what they look for. That is not, say, the CDS, which says whether your GPA or LoRs are “Very Important” (of course they are.)
This is about the personal attributes they look for, what makes them know you will take on challenges, contribute to a vibrant campus community, have impact on others, get along. What makes a kid stand out is the quality of their choices and thinking, through the high school years, how they chose to commit their energies and that they made a difference- some of this at their schools, some in their communities, and also in pursuing their own goals. It’s also how you present yourself in the app. How will you show that by writing about your parents lack of degree or a medical challenge or telling them your extended family is provincial? Think about it.
In the chance thread, you still don’t note what your activities actually are. If you want STEM, have you done math-sci and academic things? If you want a medical future, what have you done for others? You said you may get an internship- can be good- but what? The language win adds a nice note
Btw, colleges won’t diss you for taking the ACT a second time. Depending on your sub scores, you may want to try to improve a category, sure. But the 35 is good. In general, it can be good to show persistence. The problem we cite on CC is overdoing it- the proverbial kid who thinks only a 2400 is magic and goes after it multiple times. That can be a thinking and judgment problem.
No, URM is not 100%.
