Which university is easier to get into?

I'm only in grade 9, but I would really like to have a few schools in mind right now, so i can set a goal. :) SCHOOLS; Harvard University Yale... show more Out of the following schools, which is the easiest to get into & what would my GPA have to be (approx.) and what would some of the requirements be to get in ?

Like, if I take a few applied classes in grade 10/11 would it lower my chances in getting into one of those schools? ALSO, Does grade 9 really matter?

Because I'm not doing to great this year, I just wasn't ready/prepared for high school. But if i do better in grade 10 and pretty good in grade 11 & 12, would a school look at grade 9 and reject me?
