I am in an online program at South Univ. in the pathopysiology class We have message board postings minimum of three a week, they are typically a page to page and a half each, one case study with a care plan they range 4-6 pages each and a term paper each week on an assigned condition or symptom package. there are no exams. I did my BSN on line as well and find that I learn more in the paper writing classes as I am using multiple sources and not tied to the text. the text books are outdated by the time we get them anyway.
