You probably know what a tool is. What's different here is which tool answers which kind of learning question and mixing them up gets you a confident-sounding answer that isn't actually grounded in anything real.

Ask web_search how you're doing on XLOOKUP and you'll get generic advice, not your actual practice history. Ask notion_page about new resources and it'll just tell you nothing's there. It only knows what you already wrote down.

The next three labs put each one on a genuinely different problem: finding a resource, reading your own notes, and reading your own scores.
