Doing well on the analytical reasoning section of the LSAT is primarily a function of reading the questions carefully, diagramming the problems neatly and thinking through the answers logically in a step-by-step fashion, without trying to skip ahead. The LSAT analytical reasoning section is the one that causes the most apprehension on the part of test-takers because of its unfamiliarity.
The LSAT analytical reasoning section is also known by the colloquial name "logic games," which is an accurate description of the question. Each question is a test of deductive logic. The questions are often worded in a tricky manner, requiring the test-taker to decipher the impact modal words, like "must" and "could," have on the answers in order to answer correctly. Most people are unable to answer the analytical reasoning questions without drawing diagrams. Those planning to take the LSAT should practice their diagramming technique and learn to draw the diagrams neatly because there is little space for them on the LSAT pages. Diagrams should take note of whether a given entity mentioned in a test question has a fixed position in the diagram, is categorically banned from a position or has several alternate positions. Each question in one of the logic games adds a new rule to the game, and that rule must be posited against all the rules already given to come to a correct solution.
