Go read this from MIT:
Then read this:
The latter refers to students piling on APs to ‘show’ their passion/talent to the AOs. In these posts, and many other places, MIT is pushing back against the ‘more is better’.
I am happy to accept that you are a math prodigy, and you took those courses that young b/c you loved math & your parents let you b/c they saw that you were happy doing them- but there are parents who would think ‘this is how I get my kid into MIT- I push this unusually able kid to do all these impressive things.’ MIT is clearly, explicitly saying “don’t”. So, showing that you could do advanced math really young is not, for them, a hook. They want to know that who and what you are now is a good fit for their university.
