Hi bajgmat1139,
Since you are just starting out your GMAT prep, you should first
familiarize yourself with the GMAT exam and then take an
MBA.com practice exam. The results of that exam will give you a good idea of what to expect on the GMAT as well as a baseline GMAT score. The scoring data from that practice exam will help you determine how long you will need to prepare, to achieve your GMAT goal score.
In regard to resources, there are many options available, ranging from classes (in person and online) to textbooks to private tutoring (in person and online) to online self-study programs. If you are looking for a self-paced prep program, you may consider using an online self-study course. Self-study courses typically provide detailed study plans and have granular analytics, so you can easily track your progress as you move through the course. By being able to track your progress, you will remain more engaged, and you'll be able to forecast when you are truly ready to take your real GMAT. If you are unsure of which program to choose, check out the verified review section here on Beat The GMAT.
I am happy to provide some more advice, but would like to learn a bit more about your GMAT experience and MBA goals. I have a few questions:
1) For how many hours a day can you study and for how many months?
2) To what schools do you plan to apply?
3) What deadlines are you targeting?
Also, I wrote a detailed article that provides some actionable steps that you can follow
to help achieve your GMAT score goal. .
