For some reason I was expecting that a sim who got A+ in all 12 subjects would get the Honors. But no. My sim hat only A+, but still graduated with "only" A+. Not sure what more she was expected to do...
That could be. Mine had only level 1 skill in the subjects they were going to take before they enrolled and 7 to 9 when they graduated. I also had them sit in on skill classes in their off time.
