Auckland Wall is a student-run community for University of Auckland students in Auckland: course reviews and difficulty ratings, a student forum, campus events, clubs and societies and a marketplace. Anyone can read it without an account; posting, commenting and writing reviews need a verified university email (aucklanduni.ac.nz / auckland.ac.nz), so what you read comes from enrolled UoA students.
571 UoA courses have student reviews here. Each course page gives an overall score, difficulty and would-recommend ratings, merged from reviews written on Auckland Wall and public sources such as StudentVIP and Reddit.
Many posts are written in Chinese — the community started with Chinese-speaking students — and the app translates posts and comments into English.
Auckland Wall is an independent student community and is not affiliated with University of Auckland.
