New GRE Pattern from 2011
ETS has announced major changes to GRE in 2011.
The following changes will take place in 2011:
1. More questions on reading comprehension will be added.
2. Analogies and antonyms will be removed from the test.
3. The scoring range for each section will be 130-170, with score increments of one point instead of 200-800 (with score increments of 10 points).
4. GRE test takers will be allowed to use calculators issued by ETS.
5. Unlike the current scenario where the test taker can not skip any question, the new format allow test takers to skip questions and come back to them later and review answers before submitting an entire section.
6. More questions on data analysis will be added.

Tips To ace This Semester (Follow Atleast Few)
How To Plan This Semester
SQ3RThis approach helps you get the most out of your reading. It will help you create notes from your reading from which to study.
1. Survey: Carefully pre-read the chapter. Look at the title, subtitles, boldface and italics, graphs and diagrams, summary and/or conclusion, and questions at the end of the chapter.
2. Question: Reading is a thinking process; inquiry makes you an active reader. Formulate questions before you read. Convert titles, subtitles, etc. into questions. WRITE THESE DOWN!
3. Read: Thoroughly read the chapter and fill in the answers to your questions as you go along.
Important: Read for meaning, not only the answers! Write down any information you sense is important.
4. Recite: Talk to yourself. Read your questions, answers and notes out loud. Translate key ideas and new terms into your own words. Research any answers or information that don't seem clear enough.
5. Review: Reread your notes as often as possible. Frequent review enables you to better retain the material.
BE FLEXIBLE! At first go through SQ3R step-by-step, and later alter it to suit your own purposes and style.
