Likes: I wake up happy to go into school. All I have now are clinical procedures with scattered rotations. I liked that during the first two years, it was like high school all over again. You know everyone and actually interact with your classmates a lot (unlike a large undergraduate school). I like that my education applies to what I do daily. While, things seem irrelevent when you're doing the "basic sciences" during dental school, it all pans out to be very applicable (not counting brachial plexus et al.) I like how my school prepared me VERY WELL clinically. Though, there is still a ton to learn after dental school, I am 100% confident I could graduate today, enter private practice and succeed in my endeavors beyond dental school.
Dislikes: every school has its issues. Administration, curriculum unnecessaries, whatever. For Tufts, it seems to be that administration can be too progressive at times. Essentially, just when you figured out how to work the system, they decide to try something new based on student feedback from previous surveys and such. While, it's nice to be on the forefront of education, sometimes it happens without any real need.
Regrets: that I didn't think of this profession earlier.
