This template uses the ou-tma package, which simplifies writing a TMA (Tutor Marked Assessment) for the Open University. It provides an environment that wraps each answer, commands for numbering parts and subparts of questions, and macros for mathematical entry in the styles the OU uses. The six-page sample shows the header with student name, number and date, and explains each feature. It builds on tcolorbox, cancel and xcolor.
