The question pack is kind of a mixed bag. Some of the passages are absurdly easier than the current MCAT, whereas others are a not-bad representation. If it's a passage with some confusing figures and an experiment, that's closer to the current test. If it's a simple short passage that's more easy informational-based, then that's less representative of the new exam.
The thing that's actually still fairly similar are the questions, however. If my 4/18 exam was any representation, you should still expect to see questions that are a mix of almost pure recall, some inferences based on the passage, and some tricky analysis of subtle points in the experimental procedure. The old question pack will give you an okay-ish representation (if a little light on the tricksy bits) on that front.
Finally, the verbal is the same as it ever was. The verbal question packs are very good for that and I'm highly recommending them to all of my own students.
Good luck!! 🙂
