You learn it, then forget it, how do you make cloud concepts stick?

Keep reading, and don't miss the expert sessions where concepts are broken down. Use a variety of materials, follow good blog posts or YouTube videos for deeper explanations, and take notes during every study session, on paper, a jotter, or a digital notepad. Revisit those notes at intervals through the day.

Retention isn't talent; it's spaced repetition and notes you actually go back to.
