Best way to address DS weakness? 28 Jul 2007, 14:53

I'm going through the errors I'm making and simply getting killed on DS problems. I'm getting questions correct for PS that are the same principles, but when it comes to DS I choke. :oops:

Do I just need to do more of these to get used to them? Revisit principles I'm missing?

Any and all help would be appreciated.

Same problem here. I decided one of these days to track how I am doing in each section and I was surprised to see that I suck bigitme in DS. I am not doing that bad in other sections except for Permutation/Combination problems.

One other thing I noticed is that I tend to see DS as a way to gain time in the quants section and rush through them. After all I dont need to calculate answers in all cases. Now I am trying to give DS its due. And I also noticed that when I dont write equations down, I almost always screw up.

So my strategy for DS would be to not rush through them and write down every damn condition I think of, in the paper. I'll let you know next week whether it works or not.

So far so good, but its too early to tell.

good luck! I too seem to make a few less bonehead moves when I jot down what I can figure out.

Anyone else?

On DS number properties, make sure you sonsider all the types such as negatives, fractions ,zero, positives ...believe me this will greatly improve your hit rate. There is a stivky on Math forum on selecting numbers on number properties questions.. go through it.its awesome.

For Ds questions you also need to read the question and translate what it is asking for in your words. When you rush or jot down items without totally understanding them, you will make mistakes. Aim for 100% comprehension before you write anything down. It takes a few seconds more to do this but it pays big dividends in both reducing errors and in finding time saving short cuts.

I think combining what Trahul and rlvesco have written is the correct approach. Spend the first 30 seconds considering how you are going to attack the problem an what the question is asking, but don't assume +, -, and/or integer unless specifically stated in the question.
