CAIA Workbook

I’m curious if those who passed Level II (congratulations) can provide insight on the CAIA workbook. I did NOT use it for Level I or Level II. I passed Level I comfortably on the first try but just failed Level II. I studied for more than 200 hours, did half of the online classes but probably wasn’t as prepared as I was for Level I. That said, I need to do something different on the retake. The obvious thing is to study more. But between work and family, I have only so many hours in the day. Looking to maximize the time. Any thoughts on the CAIA workbook?
