If you have time and start very early reading Harrison Internal Medicine, is that an overkill? is that productive at all?
How much time exactly do you have?
I don't think "overkill" is the right word. I would say not the most efficient use of your time for the sake of the boards.
are you just starting 3rd year?
For 3rd year purposes, if you want to really be strong in your IM clerkship, I would suggest reading step up multiple times and really knowing that book. It's about 500 pages. Harrison's is what, 2500? You will read all of that in depth stuff and probably not retain it well the first time through. I'm not saying it's a bad idea, but I don't know that I would have had the free time at any point during 3rd year to put a dent in that book. If you can get through step up a couple of times prior to medicine you will be well ahead of the game.
way, way, way over. it's great to look stuff up that you can't figure out from other sources or tie in diff info/diseases. stick with step up for medicine (it's my favorite) or FA series, secret series (good clinical reading), boards and wards, pocket medicine (IM rotation favorite), recall series (good for pimp) or any usmle step 2 book. some topics are presented better than others. if you absolutely love harrisons' and must read it, use the baby harrisons' or switch to cecils. it's a little easier read for the the time you've gotIf you have time and start very early reading Harrison Internal Medicine, is that an overkill?
