I guess this all depends on the quality of the lecturer. IMO, a good lecturer should make you absolutely not want to miss. A good physiologist, for example, can teach physiology to a two year old. One time being in lecture with such a professor, and you essentially know the material. Just a quick glance for review before exams to make sure you have the minor details correct... was glutamate or glycine in this instance, for example. A good pathologist should make disease states tie in to every other subject in a logical and memorable way, and give you "eureka" moments that you won't find in Big Robbins. Hence, pathology should be easy with a good lecturer. Anatomy names/structures/locations you really have to teach yourself... no school (I hope) is going to let the professor stand in front of the class and point to structure and drill the class on their names for hour after hour. That's what netter and anatomy lab is for. Anatomy lecture should be for function, key clinical correlations, important innervations, and nuggets of insight into how to approach the memorizing aspect (as well as insight into what boards consider relevant). No sense learning whether the transverse cervical artery comes off the thyrocervical trunk, ascending cervical, or inferior thyroid most often if boards are just going to ask you FOOSH three times.
So, again, IMO, it depends on the quality of lecturers. Obviously not every school is going to have the above star professor for every single subject, so figure out which ones are and are not and schedule your attendance accordingly. With a great professor, sitting in class should be nearly sufficient to learn all the relevant information.
