SENDING SAT/ACT SCORES QUESTIONS

I just sent it to the code. Because it says that it takes 1 to 3 weeks for them to receive it, does this mean I should wait 3 weeks before sending in my CSU apps or can I send the apps in right now even though CSUMentor hasn’t received my scores. Will the official scores be sent to all CSUs through CSU mentor eventually anyway even though I already sent my apps in?
