Can I get my other Sims to attend school at the same time as my main Sim?

I like the pick your own classmate mod but the issue I feel is there are 24 premade teens goth,landgrabb so the least they could have done was set the lot limit for them. I would have loved to see them all at once at school with at least 1-3 spots for cc sims that is my biggest disappointment with the pack. If anyone knows a way around it let me know I sorta don't want to play without it I like to play hookups and drama but I need all the teens to attend school for it.
