Any of your homework papers which you do not collect during the term will be retained for a period of one year following the end of the term. If you do not collect them by this time they will be (eventually) destroyed. Please make sure to contact me to get your papers within this time frame if you want to recover them.
Final exams are not returned but may be examined during this one-year period, after which they will be destroyed.
