CARS Help

This is probably a silly question but are the AAMC CARS question packs representative of the real exam? You might be thinking, of course they are, since they're made by AAMC. But they're sooo hard, i literally get like 1-2 right per passage. I do considerably better on other material from prep companies (khan, kaplan I get like 50%, still sucks but better).

Is the real thing as hard as these question packs? It seems like I always misinterpret the passage's main idea for one that's similar...
