To my understanding, both sims can gain any skills anytime they want but can only make money from the two designated skills (per sim). While training for the skills (not the money making ones), all items/produces can be created but not sold. Only items created with the money making skill in that specific billing cycle can be sold, right? Regarding "If your Sims max their designated unique skills for earning money, your score multiplier goes up", do the said skills have to be maxed out DURING that specific billing cycle? Also, during moving, can the furniture be sold?
Sorry, as I have mentioned before, I am a little slow.
