For a week, from March to early April, I was on a visit aimed at exposing student leaders to the implementation of free higher education in Brazil. So pronounced the tour organisers, En-novate (“Case study: Brazil’s free education”, March 31).

I was in the company of 12 student representative council (SRC) members, two from each of the following institutions: the universities of Cape Town, KwaZulu-Natal, Pretoria, Western Cape and Witwatersrand as well as Nelson Mandela University.
