In Linux place file under:
~/texmf/tex/latex/OpenUni/ou-tma.cls

and then create your TMA with something like:

\documentclass{ou-tma}

\student{John Smith}
\email{john@example.com}
\identifier{B1234567}
\course{MST124}
\coursetitle{Essential Mathematics 1}
\tma{0} %UPDATE

\usepackage{amsmath}

\begin{document}

\titlepage

\question  	%1
\subquestion	%a
\subsubquestion	%i

Question 1. a. i.

\subsubquestion	%i

Question 1. a. ii.

\subquestion	%b

Each question, subquestion and subsubquestion is also a pdf bookmark with an appropriate title.

\question		%2

Question 2. New questions start new pages.
