I switched around some wording for clarity's sake, and made a couple of suggestions if you want to add more detail.&nbsp;<br /><br />I would also suggest referring to the professor as Professor X (or Professor some other letter, because of the X-Men connotation), instead of the abbreviation. That's just a personal preference though. It works either way.<br /><br />Let me know if you have any questions.<br /><br />Thank you!
