Educational practice exam platform — Saber 11 Practice Exams: From 92 to 1.4 Seconds in Reports

The challenge

The practice exams ran on Laravel 10 and Angular 15, on a private server and shared hosting. The audit report took 92 seconds and ended in an error, and the reports table froze the browser.

The solution

The platform was upgraded to Laravel 13 with PHP 8.5 and Angular 22, on MariaDB 13 in containers. The 3,062 users, 40 institutions, and 74,750 responses were migrated with identical counts and CRCs. The report dropped to 1.4 seconds and the reports table to 138 milliseconds. Along the way, execution of uploaded files was blocked, sensitive data was cleaned from the logs, and route-based roles and attempt limits were added.
