Try to be an avid reader, even if you have not been in the past. Be diverse in your readings. This will not only help in writing essays in the analytical section but will also help you in the verbal section. The trick: It's absolutely essential that you get first few answers(5-6) correct to get a good score. If you get the first few questions wrong, then even if you do better on the latter part, you will not improve your score that much. So, spend little more time in the first few questions. For every questions you make right, the next questions become harder. So, don't worry if you are getting difficult questions; you might as well be making everything right!!
