Foundational Course: initial mastery?

Hamurabi

Hi folks,

I just finished the foundational course. For some of the lessons, I took it very seriously and tried to master it but then I went a bit faster and was not matriculate so I think I still need to master it or come back to it. Should I move onto the LR lessons and come back to the foundational course later or when I need to? or should I try to revise and nail it down before moving to LR.

Thanks!
