Agree with Sean. You ask most medical students anywhere and they will tell you they skip class because it is more efficient to study on their own. Lectures are a fairly antiquated form of delivering knowledge. If you have a good CBL tutor and clinical coach you will learn a lot from them in a small group setting. UQ's own model states that the lectures are only supposed to support the learning that is done in CBL and that it is a CBL driven curriculum (CBL being case based learning).
The fact that lectures are recorded means that most people do in fact skip. This allows you to not be tied down so much living near UQ for example, because there are fewer mandatory contact hours.
I watched every lecture recorded on faster speed, debatable how much I learned, but you will use a lot of the USMLE prep materials to study for UQ anyway because medicine is medicine and the USMLE prep materials are good.
Most people do like the path and histo tutorials, and the anatomy notes put together by UQ have always been excellent.
I think people expect more hand holding and delivery of knowledge but at the end of the day you just need to be an active participant in your own learning. This is medical school no one will spoon feed it to you. They will give you a framework and you need to solidify it. At the end of the day, I have 1 semester left in phase 1, and still feel that I've learned a ton here. Every semester I have built a better foundation of medicine.
