**Important**

When completing the screener, and asked to enter a number, make sure you only enter numbers, do not add CM or $ or % or any other variable.

When entering fractions, one half is entered as this: 1/2

A mixed number like one and one third is entered as this: 1 1/3 (with a space between the whole number and the fraction)

Decimals always are entered with the leading 0, for example two tenths is entered as 0.2

The result of the screener is shown on your screen immediately after submitting the information and you will also get an email with a link to the same results.
