Hi @KYLE
Nice work on your first big exercise!
Here are some comments:
- Instead of all the
<p>tags inside the addresses it may be better to just use line breaks<br>. -
<address>tags make the text automatically italic. So there’s no need to use<em>. -
<p><time datetime="2016-01-20">20 January 2016</time></p>doesn’t belong to the address and should go outside (with it’s ownsender-columnclass). - The three semester dates should also be inside
<time>elements. - For the quote on the last line you should use the
<q>element and for the source the<cite>element (instead of<em>).
I hope that help. Feel free to ask questions. 
Cheers,
Michael
