Added to the Rules:
Note: At 4 pm on the Saturday before you are due to play this household, you may switch to it long enough to enroll your heir in a term at University.
This is to avoid the situation that
@Makenziegma describes:
I encountered a terrible snag in the well-educated bloodline. I thought it would be helpful to have my sim start at the beginning of the week. However, she is not going to be able to complete her aspiration without difficulty. In the 2nd part of the aspiration she needs to complete a course with an A. The glitch is that she has an A+ average but as she finishes the class up when I switch back it does not fill that part of the aspiration for her to continue. The first time that occurred I thought she just needed me to have her aspiration set on academic when I switched back. However, this did not fix it. Not sure it is a glitch for everyone, but I am assuming it probably is. Do I need to finish this degree and have her complete another one to complete her aspiration just not start class on the weekend? Or is there another way I can fix this and save my dynasty? Thank you as always!!!
In other words, you go to your Well-Educated household, sign your Sim up for classes, and then go back to the household you're currently playing. That way, your Well-Educated Sim will have M-F for classes and be able to get grades and eventually graduate. You may lose scholarships, however.
