The seven signals that consistently separate worthwhile courses from forgettable ones.
After reviewing thousands of courses, excellence clusters around seven repeatable signals.

Check LinkedIn for real professional work, not just other courses.
Signal 2: updated recently
Freshness matters in fast-moving fields.
Signal 3: reviews discuss actual learning
Look for reviews mentioning specific skills or projects.
Signal 4: exercises, not just lectures
Best courses embed exercises every 30-45 minutes.
Signal 5: curriculum follows a natural arc
A narrative, not a table of contents.
Signal 6: preview lectures are clear
Watch two. If tedious, the full course will be worse.
