Taking a final another day

<p>I'm currently enrolled in a Math1A lecture & discussion and my final is on Friday, December 19 from 5-8 PM. The main problem is that my grandfather is throwing a birthday party halfway around the world on Dec. 21. That means I really need to leave campus ASAP.</p>

<p>The question is, how likely will my professor even think of letting me take my final a day or perhaps a half a day earlier?</p>

<p>Also, I'm really considering switching my Math1A lecture so that I can solve the problem altogether. How difficult is it to enroll in another lecture during the adjustment period? The discussions are pretty filled and so I was wondering whether it is possible to be enrolled in two Math1A lectures at once (like for backup until I'm enrolled into both the new lecture and discussion).</p>

<p>I really hope someone can answer my questions. Thank you!</p>
