But it will hang on OP’s own app package. That’s the concern, when there’s misunderstanding.
TM, I’ve said over and over that OP needs more than some choice between one sort of stem EC and another.
I do agree with mwfan that the ECs are light, overall and in comparison to other applicants. But more solo programming isn’t the answer. Not for one missing broader engagements and with peers, in the first place.
Nor can anyone assume any kid can figure what’s a great essay, before they know what a school looks for. Holistic means the app is more than a simple survey, not just writing whatever comes to mind. Every piece matters.
