Should I take Fourth year science?

Applying to College
1

I took biology in 8th grade and my counselor said I have an extra space in my senior year to take a class of my choice in palce of science elective. I want to take two social studies classes but someone else told me I should still take a senior science class.
(I wann major in a social science/humanities based major)
I really wanna be eligible for the Ivy League schools though!

What should I do?

Yes. Top schools want to see a 4th year of science.

Take Bio, CHem, Physics and then an AP version.

For you, take Chem, Physics (honors or AP) and then AP Chem and then AP Bio.
