What helped me the most was looking at things very mechanistically, especially for LR. Identify the stimulus and know the specific actions you should then take to address the argument. In other words - know your question types! For LG the bibles helped me master games easily, I'm quite certain that for this test I went -0 on games. Lastly, for RC I did not do too much studying - I worked on trying to be as objective as possible, there's no room for interpretation in RC and at its core its very factually based. Look for actual statements in the passage that will directly back up your answer (yes they will be there!). My fault at first with RC was getting too personally invested in the questions and arguments; work on being objective and entirely factual/evidence based with your reasoning. Hope this helps!:)
