Help: improving CR quickly (test in one week)

Hi danidan, one thing that might help you with Critical Reasoning in a hurry is to try and predict the answer. This doesn't work for questions that ask you to infer, but for strengthening and weakening questions, this technique helps a lot of students avoid tempting trap answers that are out of scope of the question. If your weakness is particularly in these question types, you might find yourself able to better focus on the correct answer by identifying the author's conclusion, evaluating the premises and predicting the missing link to connect the two. As bb noted, a week is pretty short and you'd probably get better results with a GMAT tutor, but a couple of little tricks might save you a couple of incorrect questions on the exam, and thus translate into precious points.

Hope this helps!
