👋 Hey, I'm an A-level Maths student who decided not to get the CG-50, but all my friends taking Further Maths do have one.
It's really only recommended if you're taking Further Maths. I wouldn't recommend it to students using it for standard Maths because of its expensive price, and it's a little overkill. I have never heard somebody compare them in an Applied setting, what differences do you see?
I disagree with @MindMax2000 and believe that you can learn to use it very quickly, so I wouldn't worry about that.
