I'm not all that thrilled with active school (where you follow your Sim) just because you can really only follow one Sim at a time. That's one issue I have with the active careers from GTW; by the time my Sim got home from work I'd only have a few Sim hours to get the family fed, the kids/teens to do their homework, the spouse (if there is one) to do his/her work task done, then maybe some time for a bit of fun and/or skillbuilding before getting everyone to bed.
I'd like to see three enhancements to education:
1. If you select the Meet Friends tone, you should only meet Sims in your age group (child or teen).
2. Return of private schools; schmoozing the headmaster (or maybe just out and out bribe him/her for child's admission), school hours would be shorter but homework would be harder (some active projects as well as just book study, like find frogs for Biology Lab or interview anotehr Sim then write an essay for English, that sort of thing).
3. Tying in with 2, homeschool or "study from home" options. This would be similar to the "work from home" careers in CL where you can either go to the rabbithole school or "study from home" by doing two or three assigned tasks. Your Sim could start the study from home when they reach a B grade; if grade drops below that level you would lose the "study from home' option and have to return to rabbithole class every day.
In addition, I'd like to see an active day care career, with the options for Sims to drop off their toddler(s), call the nanny or send to the current off screen day care. Not too concerned about the ohject babies until/unless we get babies that can be freed from the bassinet.
