<p>Unfortunately, there is no set answer to this question. I can remember winter semester this past year I was working on a final the evening of the last day, and I can also remember some semesters where I was done on the Wednesday of finals week. Also papers for hum classes may take you time as well; during winter term this year I was working on a hum paper while I was home after the term ended. </p>
<p>The finals are typically all given out by Monday. However, you may have too many, or need to study a lot for them, or have a difficult unlimited-time final that you need the last day for. To be safe you should book them for the Saturday after the term ends.</p>
