Looks very detailed! If you can stick to what you have outlined you should do pretty well. I have three suggestions:
It looks like you may be scheduling too many CAT exams at the end of your studying/consecutively. I don't know how you work but I personally know that I would burn out at that rate. I would suggest taking one after you finish your quant section to see how you've improved and which areas are still weak.
Another important note is to remain flexible. I'm finding some material from the
MGMAT guides much more difficult than others. Instead of sticking to my schedule, I've adapted some to spend more time on these problem areas. Just an aspect to keep in mind.
Finally I would suggest to get the OG12 book. They are official questions and are great to practice what you've learned in the
MGMAT guides.
All in all it looks like a solid plan.
Best of luck.
