Frequently Asked Questions

AI
For most UK exams, a standard scientific calculator like the Casio fx-83GTCW or fx-85GTCW is sufficient and compliant. These models offer essential functions without the complexity of graphing calculators, which are often prohibited in standard assessments.
A natural textbook display, which shows fractions and roots as they appear in textbooks, significantly reduces errors and improves readability. It is highly recommended for higher-level maths and science students who deal with complex equations regularly.
While generic brands are cheaper, they often lack the durability and consistent button response of established brands like Casio. For high-stakes exams, investing in a reputable brand ensures reliability and peace of mind, whereas generics may suffice for casual use.
