I believe the formula is 3 hours of at home study time per hour of theory lecture. Depending on your schedule and if you are doing clinicals as well- this may not actually be possible. Use all the study aids you can and use the time you have wisely. Some people I know love pediatrics, others hate it. Some love oncology, others break into tears at the thought. Some people are into community nursing or Hospice, OR or family practice. The best thing is to go into every rotation with an open mind. When I entered nursing school I thought pediatric nursing was all I wanted to do. Thank goodness I've had a chance to do a lot of different types clinical rotations because I learned that my heart is elsewhere! Hopefully you will have a chance to pick a favorite based on your own experiences. Good luck!
