I wanted to chime in here because I noticed the comment from lindt123 about reading The Economist
regularly to improve your Verbal score. I echo this idea (and not because I work here!), and also wanted to let you know that The Economist
also offers a GMAT prep program. It's 100% free for the first week, and since your test is next month, I'd recommend that you sign up and check out the program Just google “gmat economist
tutor,” and it’ll pop right up. What's really great about the free trial is that it includes a one-on-one skype session with a tutor if you have a specific problem you're looking to overcome. I remember taking the GMAT myself a bunch of years ago and wish that something like this was around when I was practicing. Good luck!
