Why don't schools in the Sims have actual grades, instead of just elementary school and high school?

Did you mean actual grades such as D+ or A- or did you mean what year of school they are attending, such as second grade compared to fifth grade? Yeah, TS4 is infamous for no depth, actual year of attendance is probably too hard and expensive to show the differences in work and work loads and tasks, projects etc.
