@noya4237 got a 3 on it, don't remember much about it but they did release the written questions for last year's one, I don't know if they released the multiple choice, actually considering may is almost over if they happened around the same as last years then there is a chance the written exam might be released for this year already since mine was on May 12th or somewhere around that, but the calculator works well

PLEASE RESPOND GCSE TOMMOROW!! : Can you do quadratic simulataneous equations on the fx-991Ex
@MathinarUK
@MathinarUK Год назад
You can’t just type in a quadratic simultaneous equation and get it to produce an answer. You need to substitute the linear equation into the quadratic and use the calculator to solve the quadratic equation.

but my teacher asks i have to show what im typing into the calculator to show to workings out but with this im just putting in the question and getting the anwser straight away, would i still get full marks on the question on the wjec gcse board
@SwiftNinja69swithwaifus
@SwiftNinja69swithwaifus 2 года назад
no you still need to show sufficient workings, but this method can be used to check your answer or help you if you don't know how to approach the question.
@MathinarUK
@MathinarUK 2 года назад
Technically, correct answer means full marks for 95% of questions. Even without working out. However if you made a typo putting the numbers into your calculator, this will result in zero marks without working out. So you use this to check that your answer is correct rather than rely on this to work out your answers

Hi, I have my GCSE exam tomorrow and it'd be great if you could answer this If the question is a high mark question (3/4/5/6) and it doesn't specify whether or not you have to show your working, will you get full marks if you show no working but get the correct answer? AQA Maths btw
@MathinarUK

The truth is yes. Correct answer = full marks Unless a question specifically states to show your working out
