Terms of Service

Last Updated: 2026-01-12

1. Introduction

These Terms of Service ("Terms") govern your use of qesx, the web application hosted at this domain.

By accessing or using qesx, you agree to be bound by these Terms. If you do not agree, please do not use the application.

The "Best Effort" Nature of this Service

This application is developed and maintained by Steve Butterfill (an academic at the University of Warwick) as a personal project to support teaching.

Important: This software is provided on a "best effort" basis. While every attempt is made to ensure security, accuracy, and reliability, this is not an enterprise-grade commercial service. It is an educational tool developed by an individual.

Errors in the Questions

The questions were created mechanically and not all have been carefully reviewed by a human.

Here is how they are often created:

  1. lecture materials (slides, notes, transcripts) plus common mistakes extracted from previous years' essay feedback given to LLM;
  2. LLM asked to produce questions and answers;
  3. quick 2am read of a small sample to check that the questions and answers seem ok.

This is an error-prone process.

Questions marked as 'reviewed' have been read by a human but mistakes are still possible.

Over time, questions are read more carefully and edited. In many cases, changes are required.
