Koobs (the Bristol Textbook Network) allowed students to sell the textbooks they own that are just gathering dust, not cash, and students needing books to rent or buy exactly those that they need for their course.
This venture successfully ended after one academic year with the scheme now being run by the University of Bristol Students’ Union. Other university Students’ Unions are looking to implement the same model for their own student bodies.
Leverage, the interns’ mentoring network: a student-run initiative, to enable to students to maximise their potential when applying for internships, by getting help from students who were in their position just a year before.
I am currently in talks with the University of Bristol Careers Service to implement the network going forward.
