True dat!
Even if you just wanna be a GP or just wanna pass you should try to absorb as much materials as possible. If you don't do that then you'll have problems with board exams, clinic... Wait till you start clinic, your oral surgery profs, clinical instructors will ask you a bunch of questions out of the blue...why a certain thing is the way it is...what's your diagnosis...what to Rx...I guarantee ya that one of those days you'll have that dumb look on your face when you couldn't spit out the answer to your OS prof or do something really stupid that your clinical instructor would shake his head and take over. Then he'll tell other profs about you! One 4th yr in my class didn't know how to do post&core "should I put the core in first or the post?" As any 3rd, 4th yr what's ferrule effect and I bet you that not many of them can answer it. Ask them about anxiety/sedation, antibiotics, pain meds and oral path!
I don't understand that some students seem be very proud that they can "pull an all nighter and pass the exam" or "study only a few days and pass the boards" Everyone can pass but not everyone can understand or master the materials, techniques...
The point is learn as much as you can, do extra readings (library books) so that you'll have a strong academic background. If your manual dexterity sucks then you better spend a lot of time in the simlab, learning from instructors, friends; otherwise, you'll be paying for it with interest when you're in clinic.
