I'm sorry, but what colleges??? My college (which is consistently ranked #1 for aerospace engineering in the US, it's not a community college or anything) leaves grade scales up to the individual professor. Even so, every single one of my professors has used either a ten or even a twelve point scale.
Um...why the nasty tone? No need .

OBJECTIVELY, the material in an honors class is more difficult than a remedial class, but the children are working at their SUBJECTIVE level. A kid can be working as hard or harder in a "lower" class based on their God-given abilities...When I was in high school (20 years ago) there were no extra points for taking honors/AP courses. It was just expected that we would do the work that challenged us, and if you tested out on the AP at the end of the year your "reward" was the college credit.
