You’re in an ivy! Get it together. Get help if needed. Apply for the transfers if you think you’ll be happier elsewhere. But in the meantime, make the most of the college in which you are enrolled. You’ll have a second chance at HYP for grad school, but only if your undergrad grades and experiences show you’re worthy.
From where I’m sitting right now, it appears HYP made the right choice. So prove them wrong.
