For the possible benefit of any students reading, I think someone say 
it, rather than leave it implied: Or the difference could be an isolated 
effect of, say, some subtle difference in how one concept was first 
introduced in their respective educations, not a reflection on the 
instruction or students overall.

Aside: I think students are much the same everywhere, and most all 
students have potential to be good at this stuff.  But learning this 
stuff well requires a lot of work, and I think students generally do 
need to have sufficient sense that they're ``sharp,'' so that they stick 
with it and put in the necessary work.  Or, there is another category of 
person, who sees themself as slow but determined; that will also lead to 
learning the stuff, if the self image gets them to put in the necessary 
work.  (However, the ones who are self-assured and yet who don't do the 
learning work... they are doomed to be dim and to have few job options 
other than some kind of politician.)
