For a college student within a school at a university, what's the proper format for an email signature?

Question

What's the proper format for putting a signature at the end of an email (specifically for a college student)? I've seen different ones where the school of the university is listed, followed by the university name, and others where it is vice versa. Like these:

Full Name
Business School Name
University Name
E-Mail Address
Phone Number

OR

Full Name
University Name
Business School Name
E-Mail Address
Phone Number

Which one is correct?

Answer 1

The first of the two would be preferable.

Answer 2

I don't know for certain. In the business world the following format seems to prevail:

Full Name
Company Name
Division or Title
E-Mail Address
Phone Number

That would tend to support your second example.
