took 3 mins for 5 questions of Quant, but got 4 right out of these 5, so probably not bad deal ( still your opinion please )
Not terrible (potentially - I'm assuming 3 min really does mean 3 min and not, say, 3m 55 sec), but still a problem. It doesn't matter to me whether you got them right or not. :) What I read is: I lost a total of 5 minutes on these 5 problems. And then I think: where did that time come from and what did you miss because you made a careless mistake because you were rushing?
The problem is that almost nobody says "Oh, I'm 5 minutes behind, I'll guess randomly on two questions right away and save 4 minutes by sacrificing only 2 questions." Instead, they say, "Oh, I'm 5 minutes behind, I'll just start speeding up in general on the next 5 or 6 or 8 or 10 questions..." and now you're giving yourself many opportunities to make careless mistakes.
When people have this pattern, they come to me frustrated because their CAT scores fluctuate and they don't know why. And I have to tell them it's because they're basically relying on luck not to make too many careless mistakes. When there are fewer, the score is better, but when there are more, down goes the score... (hey, I just rhymed and I didn't even try to!) :)
Okay, so now what? You did get many of the Qs right. Can you learn how to get them right in 2.5m instead of 3m? Go back and figure that out. Which parts took you long? Why? What do you need to do in order to be more efficient next time? Etc.
And if there are some where you say - nope, I'm never going to be better than 3m30s on this one, even though I know I can get it right... well, then, get it wrong in 1.5 or 2 min instead (learn how to make an educated guess!). Because the potential harm in spending the time is too big. (Plus, think about this: when you have to spend 3+ minutes on a problem that really does have a 2m solution - but you don't know what it is - then what are the chances that you're going to make a mistake or get tangled up and miss it even if you do actually know how to do it and might sometimes get a Q like that right?)
Yes, 3 tests is enough to indicate consistency (assuming that you did mimic official testing conditions).
Okay, now I'm getting into your detail. I have a high-level question for you: are your practice scores at the level that you want on the real test? If so, then the last 10 days should be spent reviewing, not trying to get better. These articles will help:

Your score level 10 days out is about what you should expect on the real test. If there is variation due to stamina or timing issues, then you should expect the possibility that you score at the lower end of your range. It's very difficult to see a lot of improvement or fix timing or stamina problems in only 10 days.
Re: increasing stamina, you need to:
(1) take practice tests under 100% official conditions, including essays and length of breaks
(2) study in 2-hour blocks where you do not stop or get distracted or check your email or anything else for the entire 2 hours (except for one 10min break in the middle); plan out the entire 2 hours before you start so that you never even have to stop to figure out what to do next
(3) make sure that you're eating and drinking something on the breaks during the test (and while studying)
(4) practice sitting for an hour without getting up; when you do get up on a break, walk around, stretch, have something to eat and drink
