I really think that the more that I take CAT exams the more I can recognize my weak point in different sectors, in timing and in general strategies.
Very very few people can learn well in this way. The vast majority of people will NOT learn much by taking a ton of CAT exams. The people who CAN do this are typically people like me - people who like such exams, who find such exams easier than most, and who think like the test makers. (In other words, people who can ultimately score in the 99th percentile with far less prep than the average test taker.)
(q45 v30, with AWA, but I could not finish the verbal and missed 4 last questions, so I think my verbal score is somehow punished!
Yes, that would hurt your score. Did you also do the IR section? If not, that may lead to an artificially inflated score (because the practice test is shorter than the real test is, and because you didn't tire your brain out as much when taking the practice test as you will on the real test).
How much are you concentrating on your timing? If you don't make this better, then your score won't lift as much as it could. (Note: "working on timing" does not mean "learn to get everything right fast." Part of it involves learning when to get something
wrong faster so that you don't waste time that could be better spent elsewhere. And so on.)
Next, you say that your goal is to reach V40. V40 is the 90th percentile - that is, V40 is a *significantly* better score than Q45, which is 68th percentile. You're currently at V30, 56th percentile, not that much lower than your quant percentile.
I'm going to reiterate what I said last time: the vast majority of people would not be able to make that kind of leap in 24 days.
In the article that I linked last time (Developing a study plan), there's a section that talks about how to study / how to learn. Have you read that section yet? If not, do so. (Also, in that article, there's a link to other articles about timing. Read those!)
you shouldn't get this wrong!, and that question is " If I start to push myself harder, decrease my sleeping time, staying up at night and review my stuffs (In verbal only), am I doing the right job?
No. Definitely not. Cramming like this does not work - it only tires you out and makes it LESS likely that you will be able to get to your goal score. Read this:

http://www.manhattangmat.com/blog/index ... you-crazy/Again, read that "how to study / how to learn" stuff from the first articles I gave you in my last post. You don't learn more by DOING more. You minimize careless mistakes by analysis - figuring out WHY you made the mistakes that you made, and then figuring out what bad habits to break or what good habits to make in order to minimize the chances of repeating those same kinds of mistakes in future.
