NIce Calculator

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.

Calc is fine but I hate maths

Calculator works fine but if you are buying it for a level maths just a word of warning, drop it asap or if that isn’t an option then start revision months in advance. ITS SO HARD!!

Good pocket calculator

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!)

Perfect for college students, and their teachers / support staff too

This calculator was ordered for my wife to have for Christmas. It's an odd present, but she works as a Learning Support Practitioner and requested this specifically as she's lost her last 2.This is the one recommended for college students doing maths, also used by teachers and support staff.A well made and easy to use scientific calculator.The quality is good, it's a light weight. The display quality is also nice and clear.Plenty of functions are included. It's perfect for GCSE or a level maths.Definitely well recommended.
