Cheat for after school drama club promotion?

It looks like my teen is stuck in one of the levels of the drama club and even if he has the skills necessary for the next promotion and the promotion bar has the "tick" on it, he never gets promoted. It seems like a bug to me.
So, I am trying to cheat it to advance properly but I don't seem to find that cheat anywhere online.
Any idea what the cheat is?
Thanks in advance
