I really appreciate the discussion going on here, and I understand where both sides are coming from. I am already planning on doing a research project, but I would still like to do something for an hour or so every day. I start to feel physically sick when I veg out for more than a week. I think I'm leaning more towards Pathoma because there are more tangible landmarks than my reading Costanzo or BRS and not reading close enough and missing the concepts I've always missed. My school has immuno incorporated into first year, so I've covered all the normal systems and basic imuno by the end of first year. I might change my approach if the first chapter of Pathoma goes over my head though.
