I'm a student who spent years learning how to build with AI — designing things myself, having AI help build them, and then testing every screen by hand.</p> <p>That's how Vroqn was born: an AI learning workspace for school students. One place to understand concepts, practise, sit mock exams, and see exactly what to revise next — instead of a chat box with random tools bolted on.</p> <p>What's inside:</p> <ul> <li>An AI tutor that walks through doubts step by step</li> <li>Practice by subject, chapter and difficulty</li> <li>Timed mock exams with a full analysis afterwards — weak topics, strong topics, a revision plan</li> <li>A code lab (JavaScript, Python, SQL) with AI review</li> <li>Communities and a competitive arena</li> </ul> <p>But this post is really about the championship.</p> <p>The Vroqn All-Rounder Championship — 21 November</p> <p>One examination. Eight subjects. Forty questions. Sixty minutes.</p> <p>Mathematics, Coding, Logical Reasoning, Biology, Physics, Chemistry, General Knowledge and History — all in one paper. Including a live SQL challenge, written in a real code editor.</p> <p>The rules are real, because students' preparation deserves real:</p> <ul> <li>+4 for every correct answer, −1 for every wrong one</li> <li>Fullscreen monitoring and tab-switch detection</li> <li>Randomized question order</li> <li>A server-side timer nobody can pause</li> </ul> <p>The top 8 participants win a Vroqn Certificate of Excellence and a free .xyz domain for one year — supported by GenXYZ, the registry behind .xyz, which runs event support programs for student builders.</p> <p>Registration is free and open until 20 November (11:59 pm IST). The exam runs 21 November, 11:00 am – 12:00 pm IST, online from home, on Google Chrome.</p> <p>You can check it out here: <a href="https://vroqn.xyz/arena/f8cfb796-506f-4bbb-a12f-0b7c8fc74995" rel="noopener noreferrer">https://vroqn.xyz/arena/f8cfb796-506f-4bbb-a12f-0b7c8fc74995</a></p> <p>A note on building with AI</p> <p>I designed every one of the 40 championship questions myself — from alphabet-level warm-ups to live SQL. The platform was designed by me, built with AI, and manually tested against what students actually need. It's not perfect, and it grows a little every week.</p> <p>If you find a bug or a security issue, report it responsibly — verified reports get recognition on the Vroqn homepage.</p> <p>Don't just prepare for opportunities. Prepare yourself to create them.</p> <p>See you on the 21st.</p> ai webdev productivity tutorial
