Good questions. I'm going to give you a series of articles to read.
Start here:
https://www.manhattangmat.com/blog/inde ... lly-tests/And here:
http://www.manhattangmat.com/blog/index ... to-win-it/These two articles are really going to help you set the right mindset for approaching the GMAT. If you don't set the right mindset, you're going to have a tough time studying.
Next, this article will help you to develop your own study plan:
http://www.manhattangmat.com/blog/index ... an-part-1/This study plan will be customized based upon your own strengths and weaknesses. You can come back here and tell us your study plan and we'll tell you where we agree and disagree.
Note: you do NOT need to set up a plan for the whole 6 months. In fact, you shouldn't do this. One characteristic of a good study plan is that it reflects your current situation - strengths, weaknesses, etc. For that, you have to keep revising the plan.
So plan to set up something for roughly the first 1-2 months, but then know that you're going to revisit and revise. As you get further into your study, you will revise and refine your study plan more frequently - every couple of weeks.
Finally, some of the below articles are already included in the Developing a Study Plan article above, but I'm calling them out separately because they're important.
HOW you study is incredibly important. The how to learn / how to study section here has resources on how to study:

http://www.manhattangmat.com/blog/index ... -to-do-it/http://www.manhattangmat.com/blog/index ... nt-part-1/ As part of the process of developing your study plan, you will use the below to analyze your most recent MGMAT CAT(s):
http://www.manhattangmat.com/blog/index ... ice-tests/Then come back here and tell us the results of your analysis (do this in conjunction with what the Developing a Study Plan article says) and what you think you should do based on that analysis. We'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Part of getting better is developing your ability to analyze your results - figure out what they mean and what you think you should do about them!)
Expect to spend a few days thinking about this - it's not easy! And if you haven't already taken your first practice CAT, schedule that for this week-end. Good luck!
