Casio fx-CG50 for High School Students Paperback – 27 Oct. 2019

As the author himself states in the foreword, this is not the calculator you should buy for A Level, even though everyone seems to recommend it (Get the Texan) - but if you have bought one, you need this book!

The lack of a printed manual for a complicated device like this is a bit of a pain. You can use the pdf, but that means having another device to hand. The CG50 is a step-up in functionality, but also in complexity compared to the standard scientific calculators, and a lot of functions are hidden away in menus. It's quite intimidating initially, I wasn't sure how to get up the standard calculation screen when I got it.This book partially remedies that lack, but it's aimed purely at high school ('A' Level Maths in particular), as it doesn't cover say the financial functions or maintenance or programming (Python) in the book.After the slightly odd intro where he continues to laud the TI Inspire calculator, there are lots of useful examples on how to use the Statistical/ Graphing functions. The examples are often similar to the book on the 991EX. The CG50 has some limitations compared to the HP and TI versions, but it's a bit cheaper too. Its natural competition is the TI 84 CE which is very popular in the States but is poorly supported here in Europe.Useful, but probably needs a revision for the current OS 3.8 as this is based on 3.3 and there have been some changes, particularly to the statistical graphing options.

In a response to a question under the Amazon listing for this model of calculator, the author of this book states:“...the teacher who told [someone] to get this [calculator model] is an incompetent idiot! For about the same price the TI-Nspire CX (must be CX not CAS, which isn't allowed in exams) is a FAR BETTER calculator. It's a bit more powerful and it is much nicer to use…”I find this very confusing. You have to reject the author’s advice and buy the calculator anyway, in order to have any interest in buying the author’s book!

Great book and perfect companion to my Casio fx CG50.
