AM vs PM sections

Are the AM and PM exams different? Do they different weights on the topic sections?

Mirror images of each other.

They are exactly thesametopics,same number of questions of each

In terms of structure, exactly the same. In terms of difficulty, well the consensus from years past and from when I took it, and this is very subjective, is that the PM section tends to be more difficult. With Level 2, it reverses. AM section is a beast. Again, very subjective but, that’s the consensus.
