As I've been looking for a job or an internship for after college, I've learned how many employers desire writing samples and portfolios as well as a resume. Because I was a communication major, we didn't focus a ton on having a portfolio (not as much as design majors), but in my design class, I found myself wishing that we had done more design projects for my future portfolio. Now that I have to actually have a portfolio, instead of a list of things I would put in one, I find myself thinking about emailing professors and mentioning that little fact to them. (Sorry future students, I promise you'll be thankful in the long run.) So my advice to you is to take some of your work, preferable design and writing samples, and get it all together for a portfolio. See what you got great grades on or you are proud of and put it into a folder on your computer labeled "portfolio." That way, when you need it, you've got it.
Same with a resume, get it all updated and perfect BEFORE you need it. It is so nice to just have to submit the resume and not have to spend time stressing over it before it is due.
Do all of this before hand, and you'll be thankful you did.
Now I've got an email to write to former professors :)
