CASIO/Scientific calculator, genuine or fake? (Pakistan)

[@genericu2]

I never knew calculator fraud was such a big issue

[@judicatorhurayth1927]

Is so big that affects many students using it too

Well here's the issue, even after checking I bought an "original " calculator for expensive price, during 3xam it stopped working, I opened the calculator and it was fake as shown in 1:11 . Point us were not gonna carry a screwdriver everywhere and I don't think even the seller will approve of us unscrewing it

How to easily check for a genuine Casio calculator.
Applies to ES, ES PLUS (+ 2nd edition), MS 2nd edition, any MS with SHIFT+7+ON showing DIAGNOSTIC AC, all ClassWiz models
0. Make sure nothing is typed on the calculator screen
1. Hold 1 first, the calculator screen will now display 1
2. Without releasing 1, hold the 0, minus and equals button
3. Now only release 1 without releasing the other keys
On CW models a superscript 2 will appear, on other models "cos(" will appear. If you only see 1, it is not genuine or you are doing something wrong
