I think it really depends on which topic you're studying.
For example, I find doing lots of questions for Gen Nav the most efficient method to understand where I'm doing well and where I'm struggling.
But for Met I find breaking down the sub-topics into bullet points the best way to absorb the information.
I'm studying with BGS and I find the progress tests at the end of each sub-topic very useful also.
