SSC Mock Test Android App

We are building an SSC mock test platform focused on exams like CGL, CHSL, and CPO. The website should include user registration, mock tests with timer, detailed result analysis, text-based explanations, and a referral system to unlock free access. An admin panel is needed to upload tests (manual or Excel), manage users, and track referrals. Payment integration (Razorpay) is required for monthly/annual plans. The site must be responsive, secure, and copy-protected during tests. We prefer React.js (frontend), Node.js or Laravel (backend), and Firebase/MySQL (database). This is Phase-1; mobile app and league system will follow in later phases.
