In the introduction part of the first aid book, it describes how some sections, i.e. anatomy and pathology, form larger review books because of the nature of the discipline, not because of how many questions are devoted to them on the USMLE I. Therefore, the sections on the first aid probably dedicate more pages to these sections although they form a smaller and disporportionate part of the boards than the number of pages the first aid book dedicates to them.
Even though I know each USMLE I's may be different from another, it would help me tremendously to see actual number percentages (guesses) as to how many questions some people had on their USMLE I's. It will also be interesting to see the variation in question type, based on different responses by different medical students. Also, could you put the year you took the USMLE I, along with the composition (%) of each of the disciples. If I remember right, they were anatomy, pathology, biochemistry, physiology, microbiology, behavioral science, and pharmacology. Thank you for your help!!!
