Hey Product Hunt 👋 I'm Muhammad Rayan — I built UnderstandIQ out of a year-long research project on why students fail even when they study hard. The core finding that drove everything: confidence miscalibration — the gap between how certain a learner feels and how accurate they actually are — predicts learning failure better than raw accuracy. A student who scores 75% and knows exactly where they went wrong will almost always outperform a student who scores 80% but thinks they understood everything. Every platform I could find was ignoring this. So I formalized the problem into a research framework (HCMS, published on Zenodo with a DOI), then built UnderstandIQ as its first applied demonstration. I'm 16 and based in Karachi, Pakistan. This is my first Product Hunt launch. Happy to answer questions about the research foundation, the scoring math, how the cognitive archetypes work, or anything else. Genuinely excited to hear what people building in EdTech or assessment think about this.
