The best segment III courses are holistic health (western and eastern perspective ) and Human Nature Global Perspective. I wouldn't worry about that until you get to second semester but don't leave them for the last semester. There is so much to do then that one less worry is really welcomed.
As far as clinical rotations, in the first semester, I had St Lukes, others had UCSF, Laguna Honda (try to stay away from there, my classmates that went there had a very rough experience) Second semester; UCSF, St Francis, CPMC. Third semester, the Children's Oakland experience for peds and LPCH for maternity. Fourth and fifth, you have plenty of time to figure out. What I want to stress is choose your clinicals wisely, not by location or convenience. Ask around and get the best instructor and then put your whole heart in it. Your clinical instructors are the ones that will write your recommendation letters when you are trying to get a job. Also network if you are interested in the unit or hospital. If you like it and you want to work there, before you end, go to the manager, introduce yourself, thank her/him for having you there and express your interest. It will go a long way into getting a job. After the second semester you can get a job as a Nursing Assistant and you don't need the certification. I can't stress enough the importance of having your foot in the door, specially in this economic time.
As far as materials, all those pocket reference books I have found helpful and of course Saunders the Nclex review, which I consider the BIBLE of the nursing student. As a mater of fact I have a few books that I don't use anymore so if you are interested, PM me and I could meet you on campus or we will figure out a way how to get them to you. I'm not trying to sell them but I would love to pass them along to someone that is having a hard time financially and trying to make it on their own. So if you can afford them, get your own. Go to the Bookstore at the Nursing section and you will find lot's of reference books. Also if you have an Itouch or an Iphone, check the apps, they are great reference.
