I can't quite say for the DMU course since it'll be slightly different and of course with different lecturers, but generally the course is quite challenging (to be fair, that's with any uni course). At the very least, it certainly isn't "easy" as such.
There will be focus on anatomy and physiology and you should expect to revise a lot of many little details of the entire ear (there's a lot...) but you'll also have to be able to link those features to different disorders and vice versa. This will be expected of you in you career anyway so you better get used to it now.
For example, in one of last year's first year semester 1 exams, a question came up where an elderly woman had dry macular degeneration and hearing loss and from that info, you were expected to know how that would affect her day-to-day communication and lifestyle, even though we were never taught about dry macular degeneration.
You would have had to remember what the macula was and what it did, realise that degeneration of it would lead to so and so problems then figure out what those problems would do to your life.
Not trying to scare you at all, it's something that you will get used to after a while. It's just daunting at first. That question would never have come up if they didn't expect you to be able to work it out.
My timetable (at least for the first semester, hope mine doesn't change for the next) is very nice.
Mon 10-1
Tues 9-12 practical/1-4 lectures
Wed 11-1
Thurs 2-6
Fri FREE DAY
It really isn't that bad, especially compared to some degrees like the engineering courses and whatnot...
[EDIT] Yes, I did send this at this time in the morning...I'm about to head home for Christmas!
