Heh. This is going to be different for everyone. Mine is atypical. Depends on what you do and how committed you are to doing it. I'll give you my typical day:
wake up: 6:00, cycle to training 6:30, train from 6:45 to 8:00. then shower
9:00 - into hospital if it's James's. If in Tallaght, in for 10:00. Have to notify consultant that I will not be able to make ward rounds (7:00 for surgery, 9:00 am for medicine) when training.
5:00 - out of hospital. Now, this varies. Sometimes you'll be home at 1:00 pm, sometimes you might not be out til 6 pm. Depends on how much there is on that day and how much effort you put into it. I don't put very much effort into it.
6:30 pm - training again til 8:00 pm. Dinner, shower til 9:00.
Try to study at 9 pm, but often doesn't work and I just veg on the couch.
I generally do all my studying on the weekends after I'm done training (8 am - noon or 1 pm).
Of course, there's the odd party and going to see movies and stuff...studying will be the first thing sacrificed for me
. Cram during exam time. I don't do much travelling because I spend so much time training and we go abroad to race so that's when I travel. I'll do more once I'm finished with this sport (i.e. next year). And also, I'm in my clinical years which are more time-intensive than your non-clinical years. pre-clinical..you might have a day or two that's 9-5, but then you'll get a day where you only have one lecture...or even none at all. And there's loads of skipping going on anyway.
Others go travelling at the weekends, especially if there's a bank holiday weekend. Skip a Friday or a Monday of class/hospital and go for an extended stay. Others also have more evening time to put into studying. Essentially, there's pretty much ample time to do what you want.
Labs generally last 2 hours. Some may go longer.
Research...if you want to do research, usually it's during the summer. You could get grants for payment, but this usually isn't very much. Or, you could do it for free...and get "experience." The only people I know who do research during the year had connections with an American PI who happened to be setting up research in Dublin. Not that many people do research, and it's a lot of the North Americans who will seek research ops. I did research two summers - the first was with a grant, the 2nd I was paid by the department.
