Gareth’s school was selecting students for a new course in economics. As well as considering their existing knowledge of critical thinking skills, the school set them a maths and a writing test.

If a student had at least some existing knowledge of analytical skills, then they only had to pass the maths test. If they had none, then they either needed to get an excellent score on the maths test, or do well in both the maths test and the writing test.

Gareth is experienced at analytics but failed to get a place on the course.
