I did exactly what you did. You'll need to score quiet highly in your UC prep course, as it is extremely competitive to get into B Midwifery. Once you're enrolled you have access to UC library- which contains thousands of journals that you can access that will help you answer your questions. I also used google scholar.
I got got accepted into the degree however, my heart was else where and applied to Sydney Uni with my ATAR score (UC prep mark) and got accepted into another degree, so I moved to Sydney.
