I graduated over 30 years ago from a school (Duke) that had recently switched to an integrated curriculum such as the one you describe. While it is always stressful to be part of a dramatic organizational change ... this type of curriculum has been around for many years. It's not new in nursing and there are many fine nurses who were educated in schools
that had that type of curriculum.
We would all have the same lecture -- on certain concepts, such as loss, or fluids and electolytes, or whatever -- and then would go off and have clinicals in different areas and emphasize those concepts in whatever clinical area we were in. By the time we had graduated, we had spent some time in all the major clinical areas. We we didn't all spend the same amount of time in each, but we all were exposed to each and all learned to apply the same concepts to our practice. Such a curriculum often emphasizes how to think and solve problems more than the memorization of facts and those skills will serve you well in the long run.
I can understand your nervousness about the faculty's unfamiliarity with this type of learning. But change is common and frequent -- and there is not much you can do about it other than work with your faculty to meet their requirements and learn what you need to learn.
