It's got a good design, good feel and very versatile and functional. It's good quality, and very good to use in school. The display is quite good, only problem is sometimes it could be brighter. The buttons have a good feel.

The modes are incredible and very cheap (well worth money) it’s normal size for a calculator and great for GCSE and A Level although if you are doing A Level Further Maths I would say you should get a graphical calculator. Speed is quick however functionality is where it lacks. Some basic things like Pi you have to go into tools/catolog then a separate section just to get this symbol with can cost you time in the exam. Again, so close to being amazing

Calculator has lots of features and very good solar panel. Has lasted very long and still works perfectly.

Bought this for use on site visits, really good calculator, however I find it a bit odd to use as I've been using the same graphic calculator for the last 16 years (also a casio). they have updated some of the features so if you're replacing an older calculator you might have to search around a bit for some of the functions (they're all still there along with new ones!)

My abacus broke. I could only count to ten without taking my socks off.Great for GCSE Maths (and for writing 5318008 upside down).

Best calculator for GCSEsA-levels. It has many useful features and works amazingly.

Has so many functions, best calculator and is easy to use
