Hi wanabeegmater,
Your question is a bit difficult to answer without knowing more information. Did you take a practice exam to determine where you stand now? In addition to working through practice questions, try and take practice exams so you are comfortable with the test's format and time constraints. You'll get a better idea of your weaknesses as well.
You mentioned that verbal is a weakness, spend some time on that. Determine which set of problems trouble you most, and analyze ways you can approach questions that you got wrong differently.
Since your test is in one month, consider taking a course to help accelerate your progress.
Thanks and best of luck!
