The aim of this post is to gather all (or possibly almost) the questions from the most prominent GRE textbooks, at a medium-upper level. The best preparation you could have, rely upon two main fairly simple concepts: the theory and the practice. The first one is essential because without you cannot tackle even the easier question, the second one is to improve on a regular basis your skills and confidence. The two things are not mutually exclusive. The theory whether is not adequate, your main risk is to repeat over and over again the same errors, no matter how you do the practice. The practice itself is essential to build your confidence, reduce your time tackling a question and indeed, increasing your score.
