HydraNode AI: Free MCQ Exam Platform for Cloud, AI, and Big Tech Knowledge

A couple of years back we started scraping official docs from cloud providers and big tech companies — AWS, Google, NVIDIA, Azure, the usual suspects. The goal was simple: turn all that dense technical content into practical MCQ exams so people could actually test what they knew. HydraNode AI is the site I built to make that happen.

The whole thing runs as a clean, free exam engine. You pick a vendor (Google, NVIDIA, AWS, etc.), then drill down into the right branch — cloud, machine learning, deep learning, front-end, back-end, whatever fits. From there you choose the exact exam you want to take.

Each exam comes in two modes:

• Practice mode — timer runs, but you can see the correct answer side-by-side after every question. Great for learning on the fly.

• Mock exam mode — feels like the real thing. Full timer, no peeking, pure exam pressure.

Once you finish, the review screen walks you through every single question. It shows what you picked, what the right answer was, and why. Nothing confusing — just clear, clean feedback.

On your profile page you get a full analytics dashboard: how many exams you’ve taken, your average time per question, accuracy rates, and trends over time. It’s the kind of data that actually helps you track progress instead of just guessing.

I handled the entire front end, authentication, logging, and the exam engine itself. The exams stay up to date because we keep feeding fresh documentation into the system, and everything stays free for anyone who wants to sharpen their skills.

HydraNode AI turned a bunch of scraped knowledge into something useful — a no-cost way for developers and cloud engineers to prep, practice, and actually measure what they know. It’s still running and still growing as new vendors and topics get added.
