Help linking OT chapters to Studyhub for question practice

Hello everyone!
I am currently using the OT notes and lectures to study but there isn’t a whole lot of question practice on here so I will use studyhub.

But I am having a very hard time linking the chapters here to the ones there since there’s 28 chapters for FFA here and 18 on studyhub. So after say I study chapter 1,2,3 on OT I don’t know what chapter questions to do on studyhub that day.

If possible can anyone help me? I know this should be obvious but I’m just having a hard time.
