I was playing around with High School Expansion and my school was kind of empty. So, I decided to throw together a mod to fix this situation. This mod will increase the number of students in your school, as well as the number of sims during such events as Prom, Graduation and Career Day. I made several options: 18 students total/9 per class; 24 students total/12 per class). I also added 40 students option per request. (Do not recommend, though, it’s madness.) Choose only one when installing. I also moved bell ring 10-15 minutes earlier for a class because it takes more time for so many students to take their seats. Make sure to have enough desks for them in your classrooms. !Important! There is in-game limit of 20 sims per lot, a script in the mod increases it to 35. If you use MCCC settings to increase limit of sims on lot, just throw away my script, since I’m not sure what will override what.
