would timing managment skills drag the score so low as the first test even the academic level grows a lot?
Yes. If you mismanage the time enough, your score will not increase at all (and might even drop). The GMAT is not testing you on how much you "know." It's testing you on how well you are taking the test. And if you are not taking it in the right way, then your score will not increase.
In the last post you mentioned that " of the 41 verbal questions, you are only going to answer approximately 25 correctly. You are going to get about 16 wrong". I don't know how you get these numbers and what the score scale will be by doing 25 correctly?
This is true for everyone (unless you are at the very highest or lowest ends of the scoring scale). This is how the GMAT works - the scoring is NOT based on how many you get right. This is another way in which the "old school" approach is hurting you. It's really important to understand how the scoring works.
As you lift your score, you don't get more right. You get about the same number right, but you are answering harder questions correctly, so the whole
mix of problems that you are given changes.
For instance, in a classic case, let's say someone scores in the 50th percentile. Most of the questions given will be clustered in the 30th to 70th percentiles (this is very approximate). That person answered a lot of 30th to 50th percentile questions correctly but not as many 50th to 70th percentile questions correctly.
As that person gets better, he starts to be able to answer more 60th percentile questions correctly. As he can do that, the mix changes: now his score moves to 60th percentile, and the question mix becomes more like 40th to 80th percentile. He's still answering the same number of questions correctly. He's still getting lots of the lower-level questions
in his mix right but not a ton of the higher-level questions
in his mix.
This is how people mess up the timing and then kill their score: The example person from before is now capable of answering 60th percentile questions correctly. He starts seeing 70th and 80th percentile questions - which he can't answer. They're too hard. But he spends lots of time trying to answer them. Then, he has to rush on the 40th and 50th percentile questions to make up the time - and he starts to miss questions that he does actually know how to do. His overall score gets pulled down as a result and then the test ends.
The GMAT is a "where you end is what you get" test, so if, by the end of the section, his score has dropped back down to 50th percentile again, then he's going to score 50th percentile
even though he knows enough to score 60th percentile and
even though he actually was scoring up at 60th percentile for the earlier part of the section.
I think timing problem is NOT a problem that only has something to do with time,instead, it is connected with the academic knowledge you have mastered on verbal and quant section. Because it is easier to fnd out the problems and then solve them, I think advancing the academic skills on verbal and quant is the main factor to save and manage the time, . But I agree that giving up some questions is also necessary. Do you agree with my point?
No, it is not the main factor. It is A factor, yes. But the test will ALWAYS give you questions that you don't know how to do AND the test will ALWAYS give you questions that will just take too long, even if you could do them. That's just how the GMAT works.
If you don't recognize how the test works and you keep trying to do more than you should, then you will not get the score that you want to get on the test. I just told one of my students yesterday: "The goal is to make the best decisions among a series of possible investments, knowing that you can't invest in everything and that you can't go back to an opportunity on which you've already passed. Make the decision, move on confidently, no regrets."
If you want to maximize your score on the GMAT, you MUST start approaching it from that point of view. If you keep sticking to the "I have to learn as much as possible / I have to get as much right as possible / this is an academic test" view, you are going to have a very frustrating road ahead of you.
