GMAT Data Suff. Practice Tests [#permalink] New post 18 Oct 2011, 01:19
I have the Kaplan Math Workbook 5th edition. The data suff. section has 2 practice tests for these types of problems - 15mins for 25 problems. Based on everything I've read the test taker has a little over 2 minutes per problem on the quantitative section of the exam. My questions are:

1. Is 15mins realistically enough time to answer 25 DS questions?

2. What can I do to improve my time? Currently, I can answer about 80-85% correctly but given 2 minutes per problem. I would like to be able to work them faster and more accurately.

Cheers,

Cheers,

1. 15 minutes for 25 problems is very, very short for real test-like questions. I am not as familiar with this particular book as I could be, but is it possible that the questions on the quiz aren't fully test-like and are rather intended as a speed drill?

2. Two ways to improve your time are to use strategies like picking numbers and to make sure that you paraphrase the question. Picking number for variables can make math much easier than working with raw algebra, so look for opportunities to do so. And whenever you see a word problem in a DS question stem, your first step should be to convert it into a mathematical expression; it may seem like it will slow you down, but any extra time you spend translating the stem will more than pay for itself when you go to the statements.

Best of luck with your studies!
