It'll be hard for people to answer you without knowing what tool you'd be using to get your FICO scores.
If it's a credit card that is supplying you with a free score, they typically update the score once every month or thereabouts.
If it is the myFICO Ultimate $30/mo tool, it typically updates every 90 days, but might do so more often if it is the FICO 8 Classic score and if certain altertable events happen.
If the tool is Experian CreditWorks Premium and it is the EX bureau, then it is updated daily.
Etc.
