Sims can take skill class more than once after using one

[sania]

A sim can only enter a skill class only once and then they can't use it anymore unless they go for another skill, but it is also usable once for every skill. I wanna make the interactions "take charisma/gardening/fishing,etc class" is shown again in rabbit holes even though they have taken the class so they can retake the class to improve the skill. Anyone know where can I start with?

You will need a pure scripting mod with a custom TakeClass interaction for that. You can either completely replace the old interaction with one that doesn't check if the related sim took the class before, or you can add a new interaction that only gets availably if the sim took the class once.
