This morning’s posts are spot on, each in its own way. There is a ton of comprehension behind them. That’s where OP needs to catch up.
This is not as simple as what someone wants to plan for a child, how one feels a bright kid is a lump of clay to be pulled and formed. The top colleges can and do expect more than rigor and more rigor, stratospheric stats. And certainly not that the kid then started a club or a charity.
Where’s the spark?
Where’s the sense the kid has drives of his own, the awareness and energy to pursue them? OP is trying to tool a machine. That’s what she’ll get, not what the top colleges hope to cherry pick.
I think she really doesn’t get it. She would need to let go of so many preconceived notions, to help her kid as both an individual and an applicant.
And yes, among thousands of well qualified applicants, who took on the challenges and made something of them, the lack of a true foreign language can be an issue, no matter the level of college classes in the native language.
OP needs to be willing to learn what the colleges are looking for. Let go of her own singular ideas, what worked for her, years ago, what secret sauce she thinks it is. Otherwise, these discussions are futile.
