Is classed rank based on weighted or unweighted gpa?

I have a 2.7 unweighted gpa and 3.5 weighted. About what will get me in the top 10% I’m 138/538

Your class rank is based on your weighted gpa.

When you apply to universities, I think the admission offices will use your unweighted gpa.

Because ucf automatically admits any students who are in the top 10% of their class

You need to ask you HS what they use for class rank. It’s not universal and it’s not up to the college.
