FYI, this thread is almost 3 years old. I would repost your question in a totally new thread so that everyone can see you question more easily.
There are really too many factors to be considered to tell you about how your GPA will affect your chances. To be clear though, there are many people that have gotten into top schools with low GPA's. Not only can the GMAT help you overcome that, but every other part of your application. A 2.99 is not a death sentence at all. Plus, the farther you get away from undergrad, the less your GPA matters. You also have your CPA, which is a plus, and in most cases will allow you to skip some classes when you get your MBA.
For you to get a better answer I would pose your question here
ask-admission-consultants-124/ and give as much info as you can. Include:
Age
Work experience
Desired schools
GMAT score
GPA
Extracurriculars
Etc....
With this information, you will get great responses. Also, you mentioned that you are planning on getting a 700. With the GMAT being such an important part of your application, it is hard to say how you application will look without having it completed yet. A 700 is no easy task, and could take 100s of hours of studying. It might be worth while putting all your effort towards the GMAT, and start considering the rest of your application once you have that in the bag. 700+ in 90th percentile and above, you're competing with talented individuals from around the world. the difference between a 650 and 700 is large, but may only be a few questions on test day. Give us some more info, put your post in the right area, and I'm sure you'll get some great advice.
