Hi. Like many others that take the GMAT, I am struggling to finish the Quantitative section on time. I've thought of several strategies to save time on the Quantitative section:

1) For PS questions, if you cannot figure out the equations within one minute and a half after reading the question, take a guess and move on. Willing to give up on a PS question early (especially the hard PS questions) could mean you spend 1.5 minute on a PS question rather than 3+ minutes on it.

2) If you are down to the last 10 questions and are running out of time, it's better to guess on the DS questions rather than the PS questions. The reasoning is, for many PS questions, you cannot eliminate answers without doing all the math. However, with DS questions, you can at least eliminate some of the answers if you figure out points 1 or 2 are insufficient/sufficient.

3) The exception to 2) is when you read a PS question and the answers and can eliminate some of the answers off the bat. Assuming you cannot figure out the equations for this PS question quickly, this makes a good question to guess on as you have eliminated one or more answers to improve your chances.

Thoughts?
