CS Grad school- finding your "ranking"?

[poissonpilote]

Hello everyone,

I'm looking to apply to various grad schools for a PhD in CS (Artificial Intelligence). I'm French and will hold a UK B.Sc. at the end of the year.

I'm looking to find 2 schools above my level, 3 schools at my level, and 1 or 2 below my level.

Thing is, I have trouble figuring where my "level" is.

I found a couple of grad school rankings, but a) I don't know how reliable they are, and how to determine which rank is my level?

How do you do guys proceed for that? Being an international student, I can't really try to ask around to former grad students from other universities about their application...

Any help on how to choose my "level" schools would be more than welcome.

Thanks
