STACK

STACK is the world-leading open-source (GPL) automatic assessment system for mathematics, science and related disciplines.

Students type in mathematical expressions, and are not restricted to multiple choice.
STACK separates validation and assessment with an emphasis on formative assessment.
Random generation of questions is highly structured with computer algebra support.
STACK has a wide variety of input types, including line by line working and interaction with mathematical diagrams.
STACK has support for multipart questions.
STACK has support for scientific units, significant figures and libraries of chemical data.
STACK is distributed with a question library of over 4200 tested questions, including templates, examples (linked to the docs) and comprehensive question banks for engineering mathematics.

This is the official user documentation for STACK.

The main community website for STACK is https://stack-assessment.org/
A demonstration server is available in Edinburgh: https://stack-demo.maths.ed.ac.uk/demo/
Community discussion takes place on https://stack-assessment.zulipchat.com/
