Reliable and Durable: Built for Learning. Made to Last. Cheap alternatives and counterfeit copies may be available, but they often lack the reliability, durability, and curriculum suitability needed for classroom use. Our genuine calculators are built to last, trusted by educators, and suitable for the UK maths curriculum. For the best performance and long-term value, we recommend choosing an authentic Casio product. From the inventors the world’s first compact all-electric calculator over 60 years ago, genuine Casio calculators offer the durability, reliability, and UK curriculum compatibility that students and teachers depend on. Choose authentic for quality you can trust. Avoid counterfeit and fake products. Buy with confidence from a trusted source View our Model Comparison Chart to find the right calculator for you. The fx-CG50 is permitted in all UK calculator exams, further details can be found on the Joint Council for Qualifications calculator FAQ document here .
