In real life school 
has a strong impact on your future, so I think that with an overhaul it would feel more realistic, these are the things taht should be updated in my opinion:
- Types of school: is it for special needs? Is it public? Is it private? Is a boarding school? First we need variety.
- Familys can decide where they kids are going to study: there is people who has homeschooled, others who prefer private education, others who don’t care or can’t afford more than public education with help.
- Depending of the school you have diferent requirements.
- Schools can be based on methodologies or have a special program for example for arts.
- If a our zoi is a teacher we can customize their class f.e. dinosaurs.
- Active school system for each age with diferent tasks and activities.
- Zois can decide if their kids will start nursery, kindergarten or at the obligatory age and it can benefit zois
- They can drop out as teenagers and do an exam to get the level, if they want to be trainee they can do it as in real life.
- Extracurricular activities like ballet, sports, arts, acting, music…
- In some cities like Dowon they will publish the rankings every week, some zois will want to be the top student.
- You can be part of students council.
- You can get a scholarship depending of your grades, economic status and even based on your skills.
- Zois at university have to go a few days to practice in their future workplace so if they add medicine they have to go to hospital and complete some tasks.
- Zois can cheat during an exam.
- Their job and university acceptance it’s based on their grades and studies.
- You can decide how your zois will go to school by an option of parenting, they could wlak, take bus, public transport, your zois will drop them, will they go alone because they live too near or they will go with an older zoi?
- School events like school trips, proms, festivals, some universities have a special day, theme day…
