Othe med students are saying its important to learn most of the info from the essential readings (for hubs/cels mostly) which also contradicts what you guys are saying... Could someone please clarify?
There is truth in all of them, the summary: (pretty much reiterating what skyglow said above) If one is to 100% memorise (with understanding) everything in the lecture slides, readings, the lecturer's verbal bits (minus abstract examples), and is able to reproduce and/or apply all of it in the exam, then one will get full marks. For the rest of us mortals, though, the slides are far more concise and succinct in terms of the nuts and bolts of examinable material, so in the limited time that we have, if we embedded the slides into our memory and ran out of time on the readings, we would be better off than if we remembered the readings but not all the slides.
Also, for HUBS, the lecturer (Dr Buckley) has said, and I quote, "use your lab book as the guide to the level of detail you need to know, same as the GLM. If you're asked to identify a bone or a function of it, then you will need to know that. All the other details in the text that you haven't been asked to identify, you won't need that. Of course the material in the lecture is important, but I am giving you extra information to help with your understanding, so just use your lab book as the guide." For more details of what she said about the level of detail required, refer to podcast for Lecture 9 from 03:54 to 05:22.
Realistically, too, if they've mentioned something in the slides, the GLMs, or the labs, then they know that we should know that and we will be expected to be able to reproduce that, and I would think that it's more realistic (and efficient) for the staff to look in the slides, the objectives, the lab book, and the GLM booklets to see what material they should set in exam questions, as opposed to pouring over all the prescribed readings looking for abstract details, although I may be wrong...
