i'm sorry. you are mistaken. from their own site, the link that you posted:
"many students have used these guides exclusively to study for, and pass, their exams & have had great results. not everyone will feel comfortable doing his or her study in that way, but it is an option."
they make it clear that you could use these alone, but they are not sold as that. as the site states, it's simply an option. if you scour this forum, you will notice that the majority of people who used sg101, used them as a portion of their study and not their only form of study. in fact, i must retract my earlier statement where i claimed i only used the guides for a&p because i just remembered that i used vangonotes, mosby's flash cards, excelsior practice exams, as well as good old google to explain things that were not clear in the guides (which is in my original post).
in fact, i found multiple instances where the guides are actually wrong! one case involved an included practice exam of some sort and i found multiple wrong answers! multiple answers! that practice was worthless and possibly, depending on the student, detrimental.
the entire section on the cv system was so frustrating that i left it entirely for other resources as they had completely omitted the words "increases" and "decreases" when talking about blood pressure. they were just blank. big blank spots in the middle of the sentences. "vascular resistance blood pressure." is it increases or decreases? (obvious example) really helpful when you're studying the section on blood pressure, don't you think?
i'm sorry, but sg101 is not a major research and education institution. they are what they are. regular people who passed the tests and decided to give back. anyone with an analytical eye can see this. the information is loosely thrown together, at best. it is left up to the student to figure how to make sense of it all. they gathered as much info as they could and put it together in a package. bless them for it.
maybe you are like me and tend to test well. if so, that's awesome. you are lucky. i consider myself very blessed with that ability. not everyone is like that.
someone may misinterpret your endorsment and study only these guides and then fail the exam. i would hate for that to happen.
i stick by my original statement. sg101 is a group of nurses who published their study guides.
