hey,
Like JP said, the schedule is very variable. Also, I'm not sure if they've updated the website, but the courses that we're taking are in a somewhat different time-frame as they were taken last year.
In the first trimester you'll have what is called SPOM (Structural Principles of Osteopathic Medicine). This consists of Gross Anatomy (with the lab), Microanatomy (with lab, which is optional), Radiology, and Development. You'll also be taking OPP/OMM (with lab), as well as get a taste of Primary Care Skills.
Throughout the trimester, you'll generally have your first class at 8AM. In the beginning, you'll have classes ALLLLL day....until 4 or 5, usually. Then, towards the end we were getting out at 2 or 3ish, with only the occasional late day. Basically you're in the same lecture hall all day (with the exception of the labs). Lectures will start on the hour and run until about 10 of, then you'll get a 10 minute break and start on the next hour. Lunch will be at noon or 1 (usually 1). On the normal day, you'll have lecture/lab for 5 hours straight before lunch. It'll be 2-3 hours of lecture followed by 2-3 hours of gross lab, taking you from 8AM to 1PM. Bring a snack or money to get one because, as nasty as this sounds, we'd get incredibly hungry in gross lab!!
Most of the lectures are gross anatomy and microanatomy... radiology is once a week...and development is interspersed throughout the semester (sometimes you'll have no lectures, but then you might have 3 or 4 the next week). You'll also have a 1hr OMM pre-lab, 1.5 hours of actual OMM lab, and then possibly some other OPP lectures throughout the week. Gross lab was generally 4 times a week (we usually got Mondays off), and it runs between 2 and 3 hours long per day. Microanatomy lab, which had an optional attendance policy, was scheduled for 3 hours a week. We had a minimal amount of Primary Care Skills in the first trimester (maybe 10 hours or so), but we'll be getting much more of that this trimester.
We just started the second trimester, and I'm just getting used to the schedule, so I'm not sure if I can give you as complete info as I did for the 1st trimester. Generally we start at 8, but somedays we're lucky and get a 9AM start time. The major class that we're taking now is Cell and Tissue, which is composed of biochemistry, some pharmacology....basically the molecular stuff. Classes seem to run til 2 or 3, sometimes later or earlier (like I said before, the schedule is highly variable from day to day). You'll have pretty much the same OMM schedule as last semester, and there seem to be more PCS lectures as well.
Are you planning on taking the summer biochem course?? I took it and found it highly valuable. I had taken biochem in college and did really well in it, but I took the summer course to 1) meet people (this made orientation a whole lot less stressful since I knew some people already), 2) check out the profs teaching style, and 3) take a dry run through med school. I was pretty much shocked when I saw the summer course's schedule. It was from 9 to 5 every day for two weeks, but in reality that IS how med school is. The course load is very much similar to what you'll actually be getting once school actually starts. Also, the exam at the end (which doesn't count for anything) is very representative of what you'll be seeing during the regular trimester.
Anyway...I know that wasn't the most organized reply to your question, but I hope I've given you some sort of clue as to what to expect.
