This mod is huge, it's the biggest mod i've ever made. You can download a HTML to see all of it's features as there's so many it'd be hard to categorize here, but here's a summary:

Realistic School completely expands the school experience for children and teens while keeping the normal rabbit-hole school system.

Instead of one basic performance bar, every student now has individual grades for seven subjects, real percentages, a 4.0 GPA, honor roll, academic probation, attendance records, homework streaks, and full report cards.

Grades are affected by how your Sim actually lives. Attendance, homework, studying, mood, energy, hunger, skills, teacher relationships, and their social life at school can all influence how well they perform.

Students also have real classmates pulled from your save, including friends, rivals, crushes, cliques, and potential bullies. These relationships can affect your Sim’s self-esteem, school stress, friendships, and even their grades.

Parents can help by talking about school, helping with homework, attending parent-teacher meetings, or reporting a specific bully. Students who continue struggling may receive progress reports, enter academic probation, or even repeat the school year.

Please read the attached Realistic School guide so you know everything included and how the systems work.

The feature guide html file is a guide, it doesn't go in your mods folder.
