Sounds like your biggest issue is in playing separate households through the uni experience without harming anyone’s grades. I got you. Some of us have techniques for rotational play at uni that we have found work for us.
1. Play each household entirely through one term, but save before 6pm on the last day (the time at which they receive their grades and are prompted to re-enroll). Change households before this time. The student(s) will be in limbo until you play their household again. Played sims do not re-enroll automatically. Unplayed sims do.
I like to see what grades my sims got, so I save before 6pm, find out their grades, don’t re-enroll and quit without saving so I’m back at the save point before 6pm when I switch households. You use a mods that show their grades so you probably don’t need to do this.
2. An alternative method would be to play through a term and simply not re-enroll the household until you return to them. They lose scholarships (not always all of them) but I used to play this way until I realized I could work with method 1.
As for balancing a social life and studies, I don’t enroll in 4 classes anymore, I’ll do 3 tops. It takes an extra term but at least it’s more enjoyable for me and I turn aging off anyway.
I don’t see how creating a custom hood will be the solution for your issues unless you put everyone in one household which you could do anywhere except the dorms, anyway. I understand where your frustration is coming from, though.
