This is a copy of the now discontinued Casio FX-991ES PLUS, with exactly the same (advanced) functionality. this is a pretty good calculator for A-level and College studies, as long as you don't require graphic plots or algebraic manipulations this will do most of the numerical calculation you will ever need. Particularly good to have are the numerical integration and summation modes, and best of all it has a numerical solver which takes a bit of practice to get used to but is really very useful for many engineering calculations. This WECKEW model is also quite a bit faster at some calculations than Casio FX-991ES. Casio have discontinued production of these older models, so I highly recommend this clone from WECKEW scientific calculator.Easy to use, easy to see, easy to learn.and the quality is very good, it won't break even if it falls to the ground. Overall,, this clone from WECKEW scientific calculator. is a top choice for school students and professionals in need of a reliable and feature-rich calculator. With its wide range of functions, clear display, it's a valuable tool for tackling even the most challenging mathematical problems.

not as good as casio build quality!!

Great

The media could not be loaded. Whilst the calculator has a negative side the overall feel of this calculator is that it is perfectly satisfactory. I shall start with the negative. I have owned a couple of casio calculators in the past and they have all been extremely well built and sturdy to use. This calculator is the first I have used which genuinely feels cheap, the buttons are tacky However, I haven't had any trouble with breakages or buttons not registering my presses, it just seems shoddily built.On the plus side the calculator is easily adequate for most levels of mathematicians. I currently study AS maths and have found lots and lots of functions that I have never heard of, let alone need. The main reason for me buying this was the ability to integrate and differentiate to check my answers, as well as solve quadratic equations. On top of this the calculator can work with imaginary numbers, solve up to cubic equations, use matrices and lots of other niceties.For such a cheap price relative to the top end calculators I don't see the need to lash out on something which will break the bank, I can see this lasting at least up to early maths degree level if one chooses to take this route and for now I'm glad I decided to upgrade. Don't think twice about buying this (unless you feel the need to drop it from above a couple of metres, after which it is sure to break). Summary: Pros - lots of features which will be adequate for a large chunk of maths progression
