System Design Foundations

30 questions with instant scoring, a per-section breakdown, an explanation for every answer, and a list of exactly which lessons to revise for the ones you miss. Pass mark: 70%. Free to take — a free account unlocks the full answer review, gap analysis and certificate.

Suggested time: about 45 minutes. A clock runs while you answer, but it never stops you. Finish the course first, then sit this exam without the lessons open, as a real check.
