How much can low High School GPA hurt if I only plan on transferring after second year?

Pretty much what the title says. Keep in mind, I’m talking about transferring to Ivies. HS GPA wasn’t too bad (Still Top 10%).

As I understand it, transferring to an Ivy is generally tougher than getting admitted as a freshman.

So the real question is what are going to do in one year (really one semester when you start the app), that will make these schools need to have you as a student?

Your chances of transferring to an Ivy approach zero. If you were rejected by an ivy as a freshman then your chances are zero.
