What:
Refactored the
editaquestionsection inquiz_system_git/admin.phpto eager load answers for all displayed questions in a single (chunked) query instead of querying inside the loop.Why:
The previous implementation suffered from an N+1 query problem, executing a query for each question to fetch its answers. This significantly slowed down the page load when many questions were present.
Measured Improvement:
