The "strategy" you describe (to guess randomly) is only what to do if you find yourself in a situation where you are behind on time and the clock is ticking - but that is an "I'm just trying to stop myself from completely crashing and burning" strategy, not the actual strategy you want to
plan to use.
Here's what you need to do (read both):
http://www.manhattangmat.com/blog/index ... to-win-it/http://www.manhattangmat.com/blog/index ... anagement/I want to know how many maximum number of questions that i need to guess in order to reach the target score of 40 in verbal section.
And so, given what I said above, the answer to this is "That's not the right question." :)
It typically takes people at least 4-6 weeks to fix significant timing problems, sometimes longer. If you did a session or two of private tutoring, that likely was not enough time to show a measurable improvement. As to whether to do more - tutoring is expensive and I have an obvious conflict of interest in recommending it. :) The question to ask yourself is whether you feel you learned things during the sessions that were valuable enough to be worth the price.
Keep in mind:
- a couple of hours of private tutoring, even with the best tutor in the world, probably won't make a ton of difference
- tutoring is not a magic pill; you still have to do a huge amount of work on your own and be very proactive about making the most of your study time with and without the tutor
- a tutor is something like a therapist: if you don't feel like the tutor can talk to you / teach you in a way that makes immediate sense to you, then don't keep working with that tutor (it doesn't matter if s/he is nice, smart, well trained - sometimes we "click" with people and sometimes we don't. If you don't, then either find someone else or work on your own)
My big question for you: why are your practice test scores so much higher than the real test scores? Timing is obviously part of it, but you're presumably having similar timing problems on practice tests, aren't you?
