Why did the students receive an overall score for Arithmetic but no scores in some of the sub-sections?

If a student does not score high enough on a sub-section of Arithmetic, they are not put forward to the next section.

The four sub-sections of Arithmetic appear in the order as follows:

• Addition
• Subtraction
• Multiplication
• Division

A student will only be presented with the Subtraction section if they have achieved an Addition score greater than 5 years.

They will only be presented with the Multiplication section if they have achieved a Subtraction score greater than 7 years.

Finally, a student will only be presented with the Division section if they have achieved a Multiplication score greater than 8 years
