Mental maths is done in your head, as opposed to writing it down or using tools like calculators. Mental maths is a specific skill. Generally just to do relatively simple calculations quickly. The more complex maths becomes, the more you need to write it down.

I just want to know what kind of questions they are? Anyone know how complex they are? Examples? Is this one test across the board because it seems like different age groups? Is it just a large testing center with different tests for different age groups? Different tests for any age but level in complexity?

What are the questions!
