Honors dont do much for you, unless you pursue AP and want to be one of those kids. You know, annoying forgeter who talks about nothing but math, and always talks about college.
In the Schools i went to had it to where <50% was failing. Honors also gave an extra point, so F=0 or 1, D=1 or 2, C=2 or 3, B=3 or 4, and A=4 or 5, so some of the smarter kids had a 4.5 GPA.
