<p>Interesting that you created an account just to post this.</p>
<p>Tests/exams are held strictly during class time and there are no Friday classes past 5, so what you heard is definitely odd. One possibility is the professor was supposed to give the exam earlier in the week but decided to give students more time and that was the only time that worked for everybody. Another is that it’s a take home exam/paper and can be submitted electronically. If that’s the case, the professor likely granted an extension since like I said, no class goes over past 5.</p>
