4. Simulation Accuracy & Examination Warning

While our development team strives for high mathematical fidelity reproducing actual calculator firmware behaviors:

• No Academic Warranty: We do not warrant that all numerical approximations, graphical curves, matrix inversions, or statistics outputs are 100% identical to physical hardware in every edge case. Students should verify critical computations for exams and research.
• Proctored Testing Policy: The College Board (SAT, AP exams) and ACT Inc. strictly forbid internet-connected devices, smartphones, tablets, and web browsers during testing. You must purchase or borrow an approved physical handheld calculator for live exams. calc84online.com is intended exclusively for preparatory practice and homework.
