Casio fx-991CW Advanced Scientific Calculator (UK Version)

A very solid scientific calculator with all the functions needed for advanced school and college work. The layout is clear, the screen is easy to read, and the buttons respond well. It handles calculations quickly and feels like a big upgrade from older models. Great quality and perfect for exams or daily study.

I am a maths teacher and have been for 30 years. This is the most advanced calculator allowed for use in maths GCSEs at this point in time. Always good to check with the exams boards. The price on Amazon was less than I could get it through work discounts. It has a greater number of functions that the 85gt series often used in schools. Quality is good. Display is good for a calculator and the buttons have a quality feel.

had one originally but the display broke as it was launched into tarmac (dont ask) but otherwise was very durable: It was so good at its job in the ~year I had it and did so much that I bought a replacement the same day I broke it. Truly the best calculator on the market for GCSEs (and even A levels) + incredible value for money. I recommend trying one out before you buy one as (with any calculator) it takes time to adapt to it and learn everything it can do but it's a great investment and has so many useful modes, levels, tables, etc

Take the time to download the user manual and view some of the on-line tutorials. Requires some set up and configuration. Multi-function keypad layout takes some getting used to. Will need to invest some time to get the most out of the advanced functionality. Nice scientific calculator, excellent value. Would have liked a more positive key action.

Bought this for my son's A-Level maths course. Seems to fit the bill. Recommended.

Perfect for Alevel maths. Does everything required for the syllabus at school. Sturdy when dropped aswell. Highly recommend if you want to develop your maths.

As it says, Class Wiz 🪄

Mon fils est très satisfait.

Compre esta versión UK porque la española es blanca, la devolví por la única razón que la versión UK no tiene las funciones mcm y mcd que me son muy útiles, por supuesto está en inglés solo, cosa a tener en cuenta si alguien no lo entiende.

Muy completa (tablas, funciones, estadistica, matrices, etc). Valida para exámenes universidad

Perfect calculator for school.
