Hi ,
I took GMAT today and scored 580 . 48 Q and 22 V

. I was highly disappointed. My verbal was always weak , but i spent most of my study time on verbal only and still at the same point where i was 2 months back, i would say even worse than my practice test verbal scores . I must confess that i didn't follow any particular strategy to improve it and never scored good in verbal section of any practice test.
I want to get into University of Irvine or University of Davis, California, USA. Thus, I am looking for a score of 680. Now, I want to retake GMAT just after one month from now. Can someone please guide me that how can i improve my verbal . Is there any online course which is really good and helpful for non-native English speakers (as i am an Indian).
Please suggest that is one month sufficient to improve your English, and kindly let me know if you know any source that can help me to improve my verbal section.
