\section*{Aide-m\'{e}moire}

\noindent
Write down any terms, symbols, concepts, techniques, etc. that
you don't yet understand or would like to grasp better.
You can cross these out (and move them to the right-hand column) as you make progress:
it might be 5 minutes after you first write the
item down here, or it might be 5 minutes before the exam.
This will help you to keep a record of the things you
need to work on.
