Use Goljan's Pathology book with your classes. I just used Pathoma, UWorld, and FA during the year (didn't do school lectures), but this brought me to the boards with just review materials under my belt.
Goljan updates his material (the new edition is ~100 pages longer then the third) far more than Pathoma and UWorld do their own, so you have a better chance of staying up to date with changes in the examiners' attitudes/emphases.
