No offense to any Americans, but your school system sucks.
Lots of teachers base the grades they hand out on what they think of the student. In other words, some schools give 25% of students all A's, while some schools don't give a single student grades like that.

Also, if you have connections, you can come really far over there. A friend of mine managed to get a really good job, even though he missed most of his school, and got 8 F's. All he had to do was to talk to a friend of his friend, and he got a job that would have taken a nice education to get the "normal" way.
