How would you improve Teens?

My annoyance with teens at the moment is that the 'school' system is generic and pointless. It doesn't seem to matter if my teen gets good or bad grades. And the 'homework' is just a box ticking exercise. I'd love active schools! Or at least a choice of schools, like how we could send kids to private school by impressing the headmaster in TS2. But mostly I'd just like more customisation of the school life. Being able to pick classes or subjects to specialise in, so my arty Sims might get an assignment to paint a picture or brush up on their painting skill, or my computer nerd might get programming homework. Just so there's a bit more individuality and customisation. And also to feel like my Sims are going to school and doing their homework for a reason.
