Do you need 4 years science for top 25 school

If she's doing STEM, definitely. If she's doing humanities, I would recommend it. If she's doing arts, it's not necessary but it can't hurt

I feel like this answer kind of depends on what she wants to study. Most top colleges would like to see 4 years of science from applicants, especially if the intended major is in the field of STEM. However, if she wants to study something along the lines of the humanities (ELA, history, etc...), then she could probably get away with just 3 years of science. This would only work if she took more classes in humanities in the year without science. This would reflect passion into her application, which would be beneficial, especially for top schools. (This also works for 4 years of science too, in case the major is STEM related) Basically, yes if the major is STEM related, and maybe/no if the major isn't STEM related. I wish your daughter good luck!
