English idioms

Hi, Here in the video it's said "in the beginning of August" (from 3.51). Why? Shouldn't it be "at"? https://youtu.be/kE3tRw6JnHU?si=DSCXGi2BG6Xa6aaz

Could you please make some example sentences with "motormouth"?

Hi everyone. I just found out Italki sent me a message related to upgrading lesson categories. Does it apply to businnes, Kids, and test only? In my case I am a community tutor and provide with conversational and grammar lessons. Do I have to upgrade something? If someone has more knowledge on this, I would appreciate the help. Hopefully I don't need certificate to keep teaching conversational and grammar lessons here.
