Unfortunately, college and a teething baby of my own ate all of my time, so I'm going to have to throw in the towel. So, my final score is:
3 moved out,
2 sims living at home with YA req complete: 2
Other sims still living at home: 6
So, (3*3)+(2*2)+(6*1)=9+4+6=19
I could have gotten further had I not hosed up the Sims computer and not having a ton of things for school hitting at the same time. It was total madness and lots of fun
