How can we study medical from beginner ? and which book is good ?

I'm not sure what you are directly asking, but I take it you are wanting to become a medical student? Well, I would recommend starting with medical terminology so you can familiarize yourself with the terms. It is hard to recommend any books unless you have a specific category you are looking to study. You would have to choose a certain medical area, such as cardiovascular, pulmonary, ect. before you could get recommendations. Hope I helped a little!!
