Answer

Hello! This statement is correct.
However, I believe what you typed may or may not be what you intended to say.

"She is one of top rank in score."

This statement suggests that the female is ranking high in "score".

What I believe you intend to say is 
"She has a very high ranking score."
"She is one of top ranking score."
"Her ranking score is among the top ranking scores."

These statements suggests the female has a high "ranking score".

I hope this helps!

Answer

Thank you all
