Hi yoshidos,
To start, a 570 is a solid initial CAT score (the average score on the Official GMAT hovers around 540-550 most years) and a V36 means that you have a strong overall grasp of the Verbal section. This is important because many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores. Since you have just 9 weeks of available study time, you might find it difficult to hit your score goal. However, if you only require a bit of time to boost your Verbal skills, then you can focus most of the next 2 months on building your Quant knowledge, Tactics and overall 'math skills.'
With those assumptions in mind, I think that you'll have to adjust your schedule a bit. For the first couple of weeks, you shouldn't plan on taking any CATs - you won't have put in enough study time at that point to have made an appreciable improvement to your Quant skills (and you would just end up 'wasting' a couple of CATs), so you should plan for your next CAT in 2-3 weeks time. You ask a number of good questions, but there's no way to properly answer them at this point (we'll have to wait to see how your studies progress before we discuss how you might adjust them).
Have you had a chance to do a full review of this CAT? Can you define WHY you got questions wrong? In real basic terms:
After reviewing the Quant section, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
