Your decision to create your own overall student satisfaction ratings rather than believe what the students said is breathtakingly arrogant (" Times Higher satisfaction rating" September 23). After three years of study, students know precisely how satisfied they are with their courses. They will have considered many factors not covered by the 21 questions, such as subject knowledge, research skills, relevance to employment, critical thinking, team skills and exposure to the outside world.

Surely the whole point was to discover what students think, not what The Times Higher thinks they should have thought.
