How do I get my high school student to the next grade level?

Send your sim to school alone and the grade should increase.

Bug report. Please check me too.

She has been at this level for nearly a week now. How do I get her to progress to a B?

In my game I have to wait till next Monday. The game will level my sim up after 3 pm on Monday after the week which they finished eligible for the new grade. In old system (rabbit hole school) it happens on Friday when they get back home.

Note: I never send my sim alone, always going with her to school. It’s always on Monday after 3 pm when grade level up is happening. If the holiday is happening and they have day off it doesn’t matter, game will still give her new grade.

@Olalla1986 thanks for that. It's Sunday in my game and my sim will be starting hs on Monday so I guess I'll have to wait a week to see if there's a grade increase.

@Olalla1986 Thank you, my sim has just finished up on Friday.

I forgot to mention that I play on PS4 so if someone’s using mods there could be the interference that is causing problems, not sure about that. But in vanilla game, grades are leveling up on Monday after 3 pm. I see a lot of people having problems with grades so I was actually surprised that it did work for me.

Yeah it should work after 3 pm. My sims was in Granite Falls on vacation and her grades went up. And the second time after normal school day. Now she is A student. I’m doing 3rd week of school right now.
