Weekly knowledge checks for this course run on AWS Academy's own Knowledge Checks inside the Learner Lab (part of the licensed curriculum), not a separate quiz bank authored here. Per the licensing terms, no AWS Academy file is copied into this repo (see ../course-plan.md).
The graded, per-student assessment layer we author lives in the labs (../labs/) and the research instruments in instructor/ (git-ignored). This quizzes/ directory is deliberately empty (kept only for layout parity with the two sibling courses). Any original, non-AWS quiz would go here.
