100% of students
I am online-only, and I love the freedom. Basically, you have your assignments due every Sunday, and that's the extent of your deadlines. There may be a discussion board due Wednesday, but overall, I would recommend it.
I didn't think the curriculum of my Intro to Technology class was acceptable, I thought it would help me as a beginner, but it taught me a lot of things most people wouldn't need to know if they aren't going into this career field. The other thing that I don't like regards WilmU's website for their students: sometimes when I go to click on links the page is down, and then the next day it's back up again. It's enough of a hassle to be inconvenient for students.
