What has been corrected?
Oct 22, 2026, /courses/anthropic-building-with-the-claude-api/. Found in our review.
It said: Duration: about 10 hours
It now says: Duration (as stated by provider): 1 week to complete at 10 hours a week
Why: We worked a total out from Coursera's schedule (1 week at 10 hours a week) and showed it as a stated length; Coursera states no total, so the page now shows its own wording.
