Gross anatomy is not too bad, especially if you had anatomy in undergrad. The good thing is that most dental school anatomy courses dont expect you to know much about the lower extremities or the thoracic cavity. With that said anatomy entails a lot of memorization and you simply dont have the time during your first year of dental school. You are usually enrolled in 20+ units (UCSF first quarter). My advice, take an anatomy course during undergrad. This will allow you to focus on head and neck stuff in dental school, which is the area you need to be an expert in. Other classes I highly recommend are histology, microbiology, and O. Chem. For those already in dental schools, remember it gets better everyday.
