Hey, I'm taking the Core34 exam this summer 2017 and saw that a graphing calculator is allowed. This calculators are expensive and I was wondering if they make a big difference in the exam?

Thanks ahead of time to those who answer.

As far as i'm aware, as long as they haven't changed the rules recently, you are allowed a graphical calculator, it is not necessary for the exam but may help you if you struggle with curve sketching.
You're not allowed a calculator for C1 though.

The question is though, does the calculator help with your speed at taking the exam? Or just not worth it...

Depends how good you are with the content.

Well, yes. You can check whether you have the correct solutions to a trig equation, you can check whether you've applied correct transformations to a modulus graph, same with differentiation and integration.

You can also code the binomial formula into the calculators

and you can store notes and formulae that you may forget

you can also install games so when you finish early, you can play snakes

Isn't this cheating? I have a graphical calculator and my maths teacher reset it before each maths exam but nobody cared about it for physics & chemistry though, so someone could easily do this if they wanted to.

It is not necessary and of only marginal benefit.
Most of the advantages for checking answers are offered by the casio 991 ES plus.

My invigilators are rubbish and don't even know what a graphical calculator is

Some people find it makes things quicker but if you already understand what's going on there's not much point.

I use a graphical calculator. Doing C3&4 this year (edexcel). My teacher says that you don't need them, because you have to know what the original graphs look like. But her argument for using them is that it saves you time (e.g. on mine there's a quadratic solving operation etc.) You can sketch inverses, calculate roots and intercepts etc. which also helps to check your answer is correct. So not necessary, but very useful/helpful.

Ditto what most people have already said. It's useful, but not necessary.

I used mine in one of my exams (can't remember which, might have been FP2) to check the shape of a graph, and it reminded me that the range was restricted - which everyone else forgot.

I used it in the C3 and 4 exams to check my answers (eg. for roots and stuff, if you plot the graph the calculator will tell you the approximate roots). You can just as easily check them on a normal calculator though.

Tbh, imo if you're not taking stats modules (when a graphical calculator is so helpful) I wouldn't say it's worth buying one. The best thing about them is that you can programme tetris and snake onto them

(Could you maybe borrow one?)
