Written exams are multiple choice and taken on the computer. Most questions have 5 answer choices, and most of them are board style questions.
What I wish I had known prior to starting...NOTHING!!! It made it more exciting not knowing anything (haha), and also lit a fire under my tail studying wise since I didn't know anything.
Seriously though, my big pieces of advice are as follows:
1. Study your tail off at the beginning I cannot tell you how important it is to get off to a good start, especially your first semester in MFM and anatomy. Like, I would push myself to the edge at the beginning in those two classes to ensure a good start. Once you are down in a hole, it is really hard to dig yourself out, and it just makes things that much more stressful. This holds true in MFMII (2 tests, hopefully 3 for ya'll next year), BNS (3 tests), and NMSK (2 tests) as well. You just don't want to dig yourself out of a hole.
2. Take time off when you need it. Find time to relax and hang out with friends for a bit every week. Everyone needs down time, and DON'T FEEL GUILTY ABOUT TAKING TIME OFF. In my case, I didn't study near as much the second semester as I did the first semester, and my grades actually improved a touch from the first semester (doesn't happen for everyone, just my particular case...I was basically burned out and had to change what I was doing). I slept more, and I did non-med school stuff a lot more. I had a lot more fun. Weird, huh...but it shows how important rest, relaxation, and fun-time is. For the first semester and MFMII, I would DEFINITELY err on the side of caution studying wise 😉
3. Don't be scared to talk with your professors. They want to get to know you. It took me until this semester to start to getting to know some professors, and it was because I had a timid attitude in the beginning. I've eaten dinner with faculty, cooked BBQ with faculty, and sat in a faculty member's office for 2 hours talking about everything but med school. DCOM is a really special place, and a HUGE reason why it is special is because of how the faculty relates to students.
