Practice versus testing

Should practice be harder than the real test so that we are less challenged by the actual testing? And that we’ll be able to respond well?

How much tension and discomfort should we be subjected to in the course of our education? Should we expect our kids to have it easy? What are our expectations on the teachers? What is the role of parents and how should they set their expectations?

Shouldn’t parents be trained in parenting before they are allowed to be parents? Drivers need licenses, accountants have to be certified and so why do we assume humans can grow into good parents? Do we not want some minimal hygiene level of ability in parenting?
