Geoff Andrews's attempts to disparage the Open University deal with Tesco (Opinion, March 2) won't wash. Tesco customers are not "buying degrees" but gaining support for study in the same way other supermarket customers are contributing to educational resources for schools. I hope that when Andrews marks his essays he gives due regard to arguments from all sides, even if he disagrees with them.
