The only reliable strategy i know is deep detailed understanding of why and what exactly i am learning.

Be it just passing stupid ielts test or getting a job - once I invested enough time to build a concrete picture of what outcomes do i need to get and why - everything else including motivation follows organically in the most efficient way I’m capable of.

I believe there is no single best strategy of learning for a single person. Since learning is as diverse as the subjects of learning might be.
