Hi all --
Always keep in mind that MCAT physics is more about doing than it is about analyzing. This is why realistic practice is key -- the absolute gold standard is of course AAMC material, but as you move into third-party materials, it's also important to practice physics in the context of full-length exams or at least simulated C/P sections, b/c in reality you won't encounter a separate "MCAT physics" section -- instead, you'll encounter physics questions mixed in with chemistry, o-chem, and even some bio/biochem, so part of the skillset you need is being able to switch back and forth between (say) chemistry mode and physics mode within a single passage.
Of course you do need a certain level of conceptual understanding to be able to do physics problems effectively, but for the MCAT, it's often the case that the hardest part of a physics problem is understanding what exactly the question is asking and how to leverage passage info to get a plausible answer. Once you have that insight, setting up the actual equations is usually pretty simple. The MCAT doesn't tend to favor long, extremely complex physics setups like you might have seen in class, and it definitely doesn't reward being able to regurgitate theoretical information.
So practice, practice, practice -- and review! When you get a problem wrong, ask yourself why. If it's a conceptual physics issue, you'll be able to review it much more effectively in light of a problem that you just missed. If it's a passage comprehension/strategy issue, you'll be able to address that more specifically.
