Hi
First things first: It's how you use your study material and not how many study books you have that determines how well you'll do
With that being said, here is what I think about the books you have listed:
- Embryology - HY: I used the BRS embryology book in conjunction with my gross/micro/neuro anatomy courses and thought it was overkill for step 1. For my step 1 studying, I used the embryology section in FA (2011) and found it more than sufficient for my exam.
- Neuroanatomy - HY: I used the BRS Neuroanatomy book when I took the class and once again, thought it was overkill for the exam. I think the following is important in neuro (minus neuropathology, neuropharmacology, ...):
"- Know your surface anatomy well. Any rigorous neuroanatomy atlas will do. If you don't own one, the BRS neuro-book, or wiki does just fine
- Know the blood supply to the brain! Try to complete this arterial tree: Vertebral arteries --> Basillar artery --> ? --> ? ... Know try to complete this arterial tree: Internal carotid artery --> ? --> ?; know how the circle of willis works
- Know the MAJOR tracts - Spinothalamic, DCML, corticospinal, ... and know the major nuclei of the thalamus and hypothalamus (Why is the VPM important? What is produced in the preoptic nucleus of the hypothalamus)
- Know your stroke syndromes: Wallenberg, anterior spinal, pontine, MCA, ACA, ..."
- Anatomy - USMLE Road Map - should be sufficient. Just make sure you review the clinical tid-bits and not get bogged down on every little minor detail (ex: origin of peroneus longus m. vs peroneus brevis m.)
- Genetics - HY
- Histology and Cell Biology - BRS - make sure you look at a lot of H&E and EM images. Know how to distinguish between cell types (cuboidal v. columnar) and all the blood cells (monocyte v. eosinophil); personally, I think the book is too much for Step 1 studying
- Behavioral Science - BRS - Question banks and first aid really complement this book well; just make sure to go through it fast and don't get caught up in a whole bunch of the little stuff presented in the book
- Physiology - BRS - a must have in my opinion! I used this book as I went through each organ system and as your knowledge of the step material gets better, you will only "refer" to this book every now and then and not be re-reading chapters!
- Biochemistry - Lippincott's Illustrated Reviews - I thought that the biochemistry in FA is a good outline for studying biochemistry for the Step 1. I think there are some holes in what is presented in FA (when is free glucose released from glycogenolysis vs. Glucose-1-P?). Don't get bogged down in structures, names of chemical reactions (schiff-base formation, ...) but rather focus on "clinically relevant" stuff (why does skin wrinkle as one gets older? how does this relate to collagen's structure?)
- Micro&Immuno - Deja Review - I did not like this book. I used BRS micro/immuno and clinical microbiology made ridiculously simple
- Pharmacology - Lippincott's Illustrated Reviews - a great book! Pharmacology is a wild card in my opinion and I think this book is a must. This book + Question bank questions on pharmacology = amazing!
- Pathology - Rapid Review - great book. Read each section as you review the organ system. Annotate pertinent details into FA and you should be golden
- First Aid 2011 - Should be the back bone of your studying
- Kaplan Videos - I didn't use these
- DIT (is it better than kaplan vids?) - I didn't use DIT. Assuming you put in a great deal of effort studying these study materials and use FA and the question banks appropriately, I would say DIT is of little use to you. But if you really want someone to regurgitate FA (just my opinion!) and want to shell out a couple hundred $ for it, then it's your call.
- qbanks - about 50% of your studying will come from here. I would suggest both USMLE world AND Kaplan and making notes on every question that you miss/get right for the wrong reason! This will help you fill in the gaps in your knowledge!
I hope that helps!
, well congrats on getting done with the beast, mine in week
