Traditional, PBL and Integrated CoursesWatch
It refers to the level of clinical integration within the course. So the course can be integrated and traditional, PBL, or a mixture of both.
As for your question, I can't say I'm the most qualified to answer that yet. The first module we did was largely a recap of relevant A level content, and we've only just started the 2nd one (although there is a lot more new stuff in it). There is always the old piece of advice that medicine isn't that scientifically challenging - it's the sheer volume of information that makes it hard, but I can't really comment yet.
