Is "Perfect at" a viable expression? As in is it grammatically sound/idiomatic to say something like:
I am perfect at Maths.
In the same way you'd say someone is very good at it?
I have been using this construction for as long as I can remember, so it has reached a point where it just rolls off my tongue. However, I was surprised when I couldn't find any examples of its usage in dictionaries. If it's not what native-speakers would say, then how can you rephrase it so that it retains the same meaning. Many thanks
