Drama club for kids

I've done it a few times but it's pretty difficult to do the tasks every day, plus homework, plus keep the kids' fun levels up, plus work on their aspirations. If you put a child into the class, they may have to prioritise that over skills and aspirations.

I can't get my teen sim promoted to junior artiste despite having all requirements and completing the daily tasks. I also have the yellow tick to show that they're ready to be promote, but it still won't happen. Anyone know what's going on?
