Hey everyone...I am going into my first year of medical school and was wondering if I should invest in review books for each of the subjects as I go through the 1st and 2nd year courses. I'm not sure if it will be too time consuming to keep up with the textbook readings and the review books for each subject. Does anyone have experience with using subject review books throughout their first two years in order to prepare for the USMLE Step 1? If so, what are the best review books for each of the subjects covered on the USMLE Step 1? So far I have purchased First Aid and the First Aid Q & A. Thanks in advance!
