I only spent a semester in another country (in Madrid), but I felt that the lessons were not all that challenging, but they were thorough. Meaning, in my courses there we were expected to know a lot, but once we knew that material we weren't asked to manipulate it in any way that really pushed us. Confounding my interpretation is that one of my courses, as a computer engineering student, was a fluid mechanics course in the aerospace department. Then again, my US undergrad is probably pretty atypical. My school had very heavy core requirements (at least for engineering), so you had a lot of classes each semester. It tends to be a top-ranked US school, but the classes really weren't very challenging, and because of how many we took, they never seemed to go into much depth. On another note, it's not often that I reminisce longingly on my childhood, but that's exactly what happened while I was doing Cheryl's birthday. My favorite things growing up were math and logic puzzles in their pure forms, un-obscured by the tedium that accompanies them in real life. I remember Math 24 from Elementary school, Math Counts in middle school, and some brain teasers and logic puzzles sprinkled throughout both times. If you're needing some for late elementary children, I highly recommend "The Lady or The Tiger and Other Logic Puzzles"
