Hello,
Happy Thanksgiving to all, I am home for the holidays and just took one of the two GMAT prep tests. I got a 530, 31Q, 31V split at the current moment. I am currently rereading MGMAT number properties, and have the entire math set from MGMAT, Kaplan Math foundations, and Total Gmat Math.
I am reviewing the questions I got wrong, and it seems I got every single data sufficiency question wrong, I also got some geometry questions wrong but I haven't got there yet in my studies so I am not too worried about them.
I also had a ton of time left, 15+ each section, got a little nervous and rushed through a few questions.
I also about all sentence correction incorrect too, I relied a little too much on my ear.
Question is, can I get to a 700+ and are there any suggestions you can provide especially for data sufficiency questions.

I would suggest you get the Veritas Prep Data Sufficiency book, it does a tremendous job of explaining the concept. What i saw as the most helpful advice is this:
Say, you get a question like this:
Is x greater than 0?
1) when X is multiplied with Y, the result is greater than 0.
2) Y is greater than zero.
So here would be a classical DS question. Now, what i learned from Veritas, first, you need to write what question is asking, then numbers 1 and 2 below it. When i say "what question is asking" i mean, what kind of answer are they asking, value or simple yes/no answer. Note that these two (value and yes/no) are the most common, if not the only type of DS questions. So, now we go back to my example. Obviously, question is asking if X is greater than 0, so the question is YES/NO type. So, you write:
Yes/No
1
2
Now, you know that you need to answer yes or no to the question. The second best advice i can give you is the process of elimination of easier answers. You'll notice that 1) is a bit wordy while 2) is very short. I advise you to go straight to 2) and see if it can help you answer the question. It says, "Y is greater than 0" and question is whether X is greater than 0, so obviously, insufficient. You go to the paper where you wrote YES/NO and 1 and 2, and cross 2 off. Now, you move to the more complicated part, where it says that the product of X and Y is greater than 0. This again, means nothing alone. In order for XY to be greater than 0, both X and Y need to be negative, or both need to be positive. Remember that you need to forget the info from the statement 2) and consider statement1) alone. Since it is insufficient alone, cross it off. Now, you have both 1) and 2) crossed off. The only two options are: either they are sufficient together, or they aren't sufficient together. From the first statement, we know that X and Y must either both be positive or both be negative, and from the statement 2) we see that Y is positive, so, the answer is YES, X is greater than zero, or Both Statements Together are sufficient.
Point here is, always write down what kind of answer they are asking, Value or Yes/No, always write down 1 and 2, and always look at them independently. Also, always go for the easier choice first and eliminate it or decide it is sufficient alone, than move to the more complicated one, and look at it forgetting what the other statement gave you.
Still, i suggest you get Veritas Prep DS, i was terrible at it, and now i only miss 1-2...
Hope this helps buddy.
