I'd need a lot more information than what you provided in order to advice you on a path forward.
You've provided me with some data and analysis, and I'll comment on that, but you do need to do the full test analysis again (every time you take a test).
I'll copy and paste what I said below:
Also, use the below to analyze your most recent MGMAT CAT(s):

Then come back here and tell us the results of your analysis and what you think you should do based on that analysis. We'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Part of getting better is developing your ability to analyze your results - figure out what they mean and what you think you should do about them!)
In other words, you have to tell me what you think the "way forward" is. Then I'll tell you whether I agree. (We do things this way because you can't get advice from a teacher every single day about how to move forward - not unless you've got a LOT of money to hire your own personal private tutor full-time. You've got to learn how to read the data and figure out yourself how to move forward, constantly!)
From the data that you presented, it does look like DS is weaker than PS (although I'd also want to know how much time you spent on those... many times, I find that people are "worse" on DS because they answer those more quickly and make more careless mistakes). So go back over those DS (and PS) and figure out WHY you missed each one and what you would need to do in order to either (a) answer a question like that both correctly and efficiently next time or (b) make a good guess and move on without losing time.
For verbal, your performance is closer - those number differences could just be due to the specific test. But there are also usually more SC questions than any other type, so that bolsters the idea that SC is the strongest of the three.
But I have no idea which quant areas are giving you trouble or whether your CR problems are due more to assumption questions or inference questions or whatever. Dive into the data more deeply (using the article above) and give both that data and what you think the data means.
Re: how to move your score to 670 in 8-10 days - I don't know how to advise you at all without more in-depth information, but 8-10 days is also not a ton of time and improvement on these tests tends not to be linear. In short, I'll never be able to tell you, "do X, Y, and Z, and you'll improve to ABC in 1-2 weeks."
Ideally, you take the test when your practice test scores get into the range that you want on the real test - and you can't predict when that's going to happen. (If we could predict the future... well, we'd be pretty rich!) Alternatively, you take the test when you have a deadline, so you don't have a choice - but then you might not have time to get to your goal score.
