You have a few different options. I can give you a very general plan, but you will need to develop / customize it yourself. If you want more support than that, you could also take a class, which will give you set assignments and a syllabus for the 9 weeks of the course, plus a plan for when the course ends. You could also work with a private tutor - the most expensive option (by far), but any plan will be customized directly to your individual strengths and weaknesses as well as your progress over the length of your study.
If you'd like to go the route of getting help here on the forums, start here:

Once you've come up with your general plan, you can post again here to check it with us. A couple of things:
(1) Nobody can set up a 5-6 month plan from the start, not even a tutor. At the most, you'll set up about an 8-10 week plan to start; from there, you'll adjust as you see the kind of progress that you're making.
(2) The starting plan in general is to get through the strategy guides and learn all of the material in general; then you'll go back over whatever you need to based upon your strengths and weaknesses at that time.
