I have multiple friends that go to Maryland. They all have told me that D1 year is ridiculous compared to other schools. One of my friends started teeth grinding because of the stress, another who attempted suicide, and another who contemplated dropping out.
All dental schools are very stressful. However, some dental schools ease you into the curriculum while others have you running a marathon right away. I have some friends that go to Temple and they have told me that their D1 year wasn't bad at all.
