Practice on as many people as possible. It's not just about passing the practical, it's about familiarizing yourself with variations of anatomy and clinical reasoning.
Honestly, the lecture alone is ample preparation for answering clinical Q's. A lot of it comes from the ability to recall the basic sciences and integrating it with therapeutic and/or movement based scenarios, i.e, supine to sit, sit to stand, stand pivot, goni, palpating, therex, etc. Just about everything is patient specific and has more than one intervention or method of approach. I would also keep in kind the precautions and any co-morbities.
