I have only used the barrons book to study for my GRE. I feel that the math questions in Barrons are a notch simpler than that in the actual GRE. However, they are still useful as practice to get used to the "tricks" used in the actual test.
As for verbal. I studied the barrons word list diligently. I think I could remember 70-80% of the words in there. I guess about 50% of the words in the verbal section were from the word list. My vocab is really not that strong but studying the word list helps. I spent about 3 months studying the word list.
When I took my SAT many years ago, I didn't study the word list at all and I scored 600 for verbal. I hardly practised math questions and I scored 750 for quant. So my total score then was 1350. My GRE score of 1490 was a pleasant surprise. So my advice is.. study study study. Give yourself lots of time to study!
I'm still waiting for my
AWA results. For those who have taken the computer test, how long did it take for you to receive the test results? ETS website says you should get it within 10-15 days. It has been 16 days (including weekends) and I still haven't gotten it. Is it too early to call them?
