If it weren't for my mod that allows me to select which students show up at High school, I would not bother.
The reason I was excited about high school years when I first heard about it was I thought I would have more time to have my teens meet and be friends with my other teens in the various worlds.
So imagine my disappointment when the game began spawning generic townies, or sims from the pack instead of using my other sims.
The mod helped a lot, so I will most likely go to school with my sim. I am not sure if I will bother with prom though. Time is too short to actually enjoy it. It's been a while since I've played the sims. I hope the mod creator is keeping it up to date.
