Share 'Use of Level 2 English and Maths assessments for entry to NVQ3 Health and Social Care'

Hi Guys, I would be interested on your thought please, how relevant are the level 2 tests to someone who is working as a carer in a healthcare setting, and wanting to study for the NVQ 3 in Health and Social Care. My understanding was that alot of the work is carried out through observations and some writen work. How is algebra or trigonometry relevant to caring for someone?
