I would be happy to give you some tips. First I have to warn you that you shouldn't expect much to change in just a few days. If you are really concerned that this is pulling your score down significantly, then you are likely going to need some more time to study before you take the test.
The mental energy that you use is cumulative, so you're always going to be the most tired during the last section (the verbal). One way to have more mental energy during that section is to use less earlier in the test.
That means learning how to streamline your performance on the essay and IR sections, especially, since you care less about those scores.
Use this template to help make it easier for you to write your essay:
http://www.manhattangmat.com/blog/index ... no-thanks/How much have you studied for IR? You don't want to spend as much time as you do on quant and verbal, obviously, but you do need to make sure that you spend
enough time to do two things:
(1) know which questions to skip (guess immediately and move on)
(2) know the techniques to help you do the questions that you do decide to answer
Now, for quant. A LOT of people - most, actually - spend too much mental energy on quant. You know those questions on which you spend 3+ minutes? Even if you get them right, they're not worth it - because you just spent SO MUCH mental energy that you hurt yourself for the rest of the test. Do that 3 or 4 times in the quant section and you're going to crash on verbal.
So spending extra time is not just about having to balance the time within the same section. It's also about making sure you have enough steam to get to the end of the test.
If you go look at your last test, I guarantee you that you'll find at least 2 or 3 questions on which you spent too much mental energy. You'll remember them because they STILL annoy you, even now. :) Was that the best use of your limited mental energy? Clearly not, since you then can't make it through verbal.
All of what I'm discussing above is going to take time to implement - I've never seen anyone just flip a switch and get it right immediately. So that's why I suggested you might need more than 4 days to make this happen. If you CAN learn to spend your time and mental energy more wisely, though, making better decisions as you move through the test, then you'll likely start to see a payoff on verbal.
Let me know what you decide to do. If you keep your test date this Saturday, then go for the lowest hanging fruit: guess on the hardest IR questions immediately without even getting into them. Do this on quant, to some extent, too. Ideally, though, give yourself a bit more time to learn how to manage your time and mental energy more wisely.
These can help, longer term:
