She indeed wanted to know how much Ghouls differ from Humans. First questionable thing about it is, do they really give lessons about ghoul physiology & biology compared to humans. As far as I know specialist on the ghoulfront are besides CCG, scarcely spread-out people like Ogura & crew. CCG or rather Washuu's & V hold a monopoly on all this, closely keeping it to themselves.

The only thing Touka can do is compare what she learns about humans with what she knows about her own constitution, but for that to work, she first needs to study and go to school & it doesn't seem like she went through with that wish off her. Rather her other wish to open a café which predicted the coming of the King all along.
