Okay... Got it
Here's how I would go about it.
Day 1: Write
Manhattan GMAT Test 1 and review the result. Select the area in verbal ability in which you are the weakest. After you've zeroed in on the weakest are, pay attention to the following:
a) What is the maximum, minimum, and average values of the difficulty level of the questions you got in that area
b) What is the average time spend on the questions from that area
Day 2: Hunt the GMAT Club for resources you need to add strength to your weakest area
Day 3, 4, and 5: Study like your life depended on it
Day 6: Write
Manhattan GMAT Test 2
Check the result summary to see if there is an increase in the minimum, maximum, and average difficulty level of the questions from that are. If yes, then check if it continues to be your weakest area. If it remains the weakest area, spend a couple of days to study the area more deeply. If it is no longer your weakest area, pick the current weakest area and follow an approach similar to what you did before i.e. hunt for resources at GMAT Club and Study like crazy.
So overall, every five days you will take a test and analyze your area of weakness and spend time working on that area.
5 days x 6 Tests = 30 days (1 month)
This is one of the best ways in which you can prepare.
