Hey there! 2nd year nursing student at Schoolcraft. I find that the practice questions from the book are nothing at all like the tests, but the exam content definitely comes from the book. I've gotten through the program so far by literally reading every chapter assigned, even though it is definitely a lot of reading. And honestly I feel like the quality of the lecture totally depends on the instructor, not sure who you have. Feel free to send me a message if you have any more questions, hope it helped a little :)
