If you are a 100% sure you are not interested in specializing like I was you should do the following. Study just enough to know the information in the meaningless classes like biochem to pass the class and pass boards (still a grip of studying), but dont kill yourself like most people. Take time to enjoy your family or personal time and dental school wont be as bad for you as most of your classmates. Also since you are going to be a GP make sure you get a good clinical experience by doing extra cases and assisting in the residency programs available at your school in your spare time, this is a great way to expand your knowledge and get a feel for the scope you would like to practice. There is a tone of GPR programs and grades dont matter for 99% of these programs. This is what I did and dental school was not that bad for me. I learned alot clinical wise at my program as I was not stressing about the tests we had that week, and instead taking on larger cases or scrubbing in on a sinus lift with a perio resident.
I'll agree that life balance is important, and
many students miss out on that. Kill themselves for 4 years, then are surprised to find out that their DSchool straight A's did not prepare them for a career in the same way that UGrad straight A's got them to DS. They obsess over maintaining a GPA, often at the expense of real learning.
Learning, of course, is why we're in school in the first place (NOT A 4.0 GPA)
But mixoma- to say that there are "meaningless classes" is to imply a lack of value in that knowledge we gain in
understanding mechanisms- the theory, the
why. I'll agree that there are big components of the curriculum that
seem irrelevant, but I would rather be over- rather than under-exposed to material.
It's about priorities. Make it a priority to become a good clinician, a community leader, to build the practice you want to be in, to build your skill sets and competencies. Keep your grades up, but work that into those other priorities. Hint: it won't always be on the very top, unless you're a robot. Patients get edgy with robo-dentists, typically preferring a f*&#@!ng human being instead.
Grades usually correlate with learning. Usually.
And scrub in on as many of those sinus lifts /OS cases as you can while in school...the GPA-obsessed, residency-or-bust, gunner-type will rarely fight you for them, because they're too busy memorizing every step of glycolysis again

At the end of the day you will have LEARNED far more than them. As a patient, I'll pick THAT dentist any day.
