Class Calc Graphing Calculator vs Taculator 84 Graphing Calc

Test-safe calculator. Statistics • Graphing • Scientific • Matrix calculator. 100% free. No ads. No “upgrade to unlock” functions. All equivalent functions of a TI 84 calculator, Casio calculator or HP calculator. Paying $100+ for a graphing calculator is just silly. Here’s our logic: 1. We’ve built a beautiful, easy to use online digital calculator right there on your phone. 2. The problem is, that you can’t use your phone on tests, so you’re stuck paying $100+ for your calculator. 3. Not anymore! 4. With our easy-to-use Test-Mode lockdown, you can now use ClassCalc on tests. Teachers can ask students to temporarily lock their own devices* out of all outside distractions such as instagram, calls and texts, keeping students focused in class, and preventing cheating on tests. Students can leave Test Mode whenever, and once they do, the teacher is notified. *Note: Teacher only has access to whether the student is in lockdown mode or not, and nothing else. The teachers will NOT be able to control their student’s device. To get started, or to help your teacher get started, contact us at team@classcalc.com, or visit our tutorials at classcalc.com/tutorials.
