I am an older student coming back for a second career in nursing. The last math class I took was over 20 years ago. I knew I needed something that was hard care math in order to be in a position to do well. I brought a book for content math and reviewed that and it has some good practice. However, I needed more practice, so I got this book. I went over the book 3 times to make sure I knew how to solve the questions. I am happy to report that I did get an overall 85 in math. If this book can help me, it can help anyone.
