University too hard/no fun ?

I hated that I couldn't play any other households. My sim Hugo graduated with a GPA of A, but Luna failed her second to last semester and got put on probation, so I continued with Hugo and cheated Luna's degree after a week, so I pretended she did it by herself.

University in this game is not my thing. I liked it the most in TS2 where I let everyone study based on wants and fears and not everyone got an A either, but this is too stressful for me because I can't tell where we're at with the grades.
