It depends on where you are stumbling. Is it reading the graphs, or actual calculations, or something else?
doing calulations and reading graphs are difficult for me in data interpretation questions....
In some questions in the answer choices we see..
Which one of the following is true..?
Here i have to calculate all the answer choices ..especcially most of the calc. are difficult...
And reading from graphs is also difficult for me....
Reading graphs from Barron's and Kaplan are usually difficult. On the other hand, the actual GRE clearly mentions or indicates the various values on the graphs. So reading should not be a problem when it comes to the real thing.
For calculation purposes, it may help to round the numbers. For instance, if you have something like 21%, round it down to 20% and approximate the answer.
