Yep. You generally spend your first year just holding your head above water in terms of the residency itself. During second year you start getting things organized (the amount of material is massive), and in third year is when the hardcore studying really begins.
There are 4 parts that cover 3 days: Gross Pathology, Microscopic Pathology, Veterinary Pathology, and General Pathology. Gross is where they will show you images of lesions (any species, any disease, any organ - all you get told is "tissue from a dog/cat/monkey/pig/whatever") and you have to be able to diagnose it on sight and answer any follow-up questions they have - you get about 60 sec per image. Microscopic is a set of 20 slides and you have 13min per slide to fully describe all the findings and answer followup qs - so about 4.5 hours of frantic writing. Vet Path is multiple choice and covers all sorts of pathogenesis related questions (from small animal, large animal, clinical path, and then you can choose either zoo or lab animal for the last section) as well as textbooks and ~3 years of the most recent literature in the field from a variety of journals. Gen Path is the one everyone hates the most, it is cellular biology, biochemistry, physiology, etc.
They have recently altered the exam format slightly so that Gen Path is taken at the end of first year as opposed to everything at the end - sort of a qualifying exam in a way. It makes a lot of sense that way to me since it is less specific than the other parts of the exam and covers more foundational stuff.
AND I NEVER HAVE TO TAKE THAT **** AGAIN.
Thank God. It was traumatizing as hell. I don't think I ever cried so much over the course of 3 days as I did then.
