Hey Product Hunt! 👋 Excited to share the Study Hours Calculator, the latest addition to GPAConverter, a suite of free calculators I've been building for students. What inspired this: As a part-time teacher, I kept seeing the same pattern, students asking "how many hours should I study" as if there's one universal answer. There isn't. A student with two topics and three weeks needs a completely different plan than one with ten topics and five days. Most study planning advice online is generic, "study 4 hours a day", without accounting for what you're actually studying or how confident you already feel about it. The problem I was solving: I wanted a tool that builds an actual day-by-day plan, not just a number of hours. Something that takes your exam date, your available study days, and your real topic list, then figures out how to split your time so weaker or higher-priority topics get more attention, with practice sessions, review days, and a mock test built in automatically. How my approach evolved: I originally built it as a simple hours calculator, exam date in, hours per week out. But that wasn't actually solving the real problem, knowing you have 20 hours available doesn't tell you what to study on which day. So I rebuilt it around topic-level scheduling instead, with a confidence and priority rating per topic that actually shapes the plan. Along the way I also caught and fixed a real bug where topics could get silently skipped when someone entered five or more, exactly the kind of thing that made me build and test this myself rather than trust a generic formula. Would love your feedback, especially from anyone who's tried to build a study plan by hand before. What's the hardest part of planning your study time? 🙏
