I dont know how samsung failed 6 times as I passed and found it very easy!!

I mean easy and simple qestions at least 12 off them is just comensence!

So you only need 6 out off the other 12 to past, if you read the book you will past unless there is somthing wrong with you or you dont want to learn, or cant speak english then you wont pass as they ask the questions in a way that you must be able to understand english at a good level.

Good luck all
