There is an inherent problem of tests like this is the interpretation the questions and the reasons for it. For instance, there is a question about if schools should make classroom attendance compulsory. What does that even mean? For instance, if you were ultra libertarian, you may say no, because the state should not be able to force your kids to do something against your will. However, if you interpreted it differently, the same ultra libertarian might say yes, because schools that you send you kids to freely should be able to set their own rules as private organisations.
Just one example, but I've done the test twice in a row with different interpretations of some questions and got very different results. But I answered them honestly from a particular political perspective.
