About this deal

All of the models mentioned above are allowed in any exam where calculators are permitted *; there is no distinction between a calculator for GCSE and one for A-level as far as JCQ (who make the exam regulations) are concerned. You can find the JCQ regulations in section 10 of this document. functions; new functions on the ‘GTX’ model include Ratio, Digit Separator, Advanced Statistics, Advanced Tables and Variables List AtthemomentallmyanswersarecomingoutasfractionsandfractionsareuselesstomeasIneedallmynumbersindecimals.HowdoIgetittogivemedecimalanswersbydefault? IknowIcanpressthefraction->decimalbuttonbutthatgetskindaannoyingwhenyouhavetopressit everytime. Schools should be telling you to get the CW now since that’s the current model, but some haven’t caught up yet and are still telling students to buy the GTX – which is now hard to get hold of new at a reasonable price. The same thing happened when the GTX replaced the GT Plus. A lot of schools/colleges haven’t caught up with the change yet and are still telling students to buy the X versions, so at least yours is on the ball!

fx-85GTX contains additional features such as clearer display, clearer menus, faster processor and 14 additional functions. Allowed in every UK exam where a calculator can be used. Recommended and approved for Key Stages 3 & 4 (including GCSE, National and Higher, Junior and Leaving). The large Natural Textbook Display (Natural-V.P.A.M.) shows mathematical expressions like roots and fractions as they appear in your textbooks which increases comprehension because results are easier to understand. In short, the new CW calculators are a lot more complicated to use than the older X models, and don’t offer any significant improvements that I can see. thereshoulfbeabuttononyourcalculatorwhichlookssomethinglikeS<->D.sowhenyougetanansweranditsinfractionspressthatbuttonanditconvertsittodecimalsandnormalnumbers.HopethathelpsComplete the short form that accompanies your product. Please ensure that you complete all of the sections, as this will guarantee the timely processing of your return/exchange. The fx-85GTX takes the UK's Number One Scientific Calculator a step further, by offering Solar Power to ensure no loss of battery during those crucial exams. The display is certainly not like the one I had in school as it shows the calculation on the top row with the answer on the bottom which is brilliant as any mistakes can be easily seen. From the comments I’ve seen on social media from other Maths teachers, I’m far from alone in having a strong preference for the older Classwiz fx-83/85GT X and 991EX models over these new CW calculators. Casio doesn’t appear to have done much field testing of the new models before launching them on the world!

Nice large clear display, a sliding case that you can slide on and use the calculator, so doesn't get lost. For more information on what calculators are permissible in exams, take a look at my Clueless about Calculators blog post. Finally, a colour warning The calculator worked straight away, comes with a decent instruction manual and the large display is easy to read. The A-level model now has the generic equation solver function in the same place as the quadratic and simultaneous equation solvers, rather than in an apparently random position above the CALC button. The new A-level specification required the candidate to use a calculator featuring certain statistical functions that the GCSE model didn’t have, so the new standard model for A-level was the Classwiz fx-991EX. This also included some additional functions to help with solving equations, so it could be useful for GCSE too.

Reviews

The A-level models have additional functions such as solving quadratics and simultaneous equations which can be useful at GCSE too, as well as Statistics functions that you don’t need until A-level. So if there’s any chance of you continuing with Maths beyond GCSE then it’s a worthwhile investment. (You’ll probably need it if you do Core Maths too, though it does depend on which board and which modules you study. It – or an equivalent – is certainly required for the Statistical Techniques option on the AQA spec.)
