Hey everyone! 👋 I'm excited to share Attendance Percentage Calculator, part of Scorebook, a free suite of tools I built for students. I built this after realizing most attendance calculators online just tell you your current percentage and stop there. What students actually need to know is: how many classes can I still miss? How many do I need to attend to hit my requirement? What if my school requires 85% instead of the usual 75%? So this tool does a few things differently: 📊 No hardcoded requirements — pick any percentage from 50% to 95%, or set a custom one, since every institution sets its own rule 🎯 Classes-you-can-miss and classes-needed-to-recover, calculated instantly, not just a bare percentage 🔮 A what-if calculator — test "if I attend 5 more classes" or "if I miss 2" before it actually happens 📐 Every formula shown, so you're never just trusting a black-box number It's completely free, no sign-up, and everything runs in your browser, nothing is stored anywhere. Would genuinely love your feedback, especially if you're a student, teacher, or academic advisor. What would make this more useful for you? 🙏
