GMAT Strategy

I was reading someone's report on beating the gmat and they said that they skipped 4 or 5 questions. I'm pretty sure this person still scored a 750 on the exam. I'm trying to understand how much it affects us to skip questions. Should I skip quantitative questions that seem over my head or too long? Will they be replaced with a question of similar difficulty? How does skipping work? How do you skip? Do you simply not put an answer in and hit "Next"? I noticed on the GMAT Prep software that there is no "Skip" button.

I typically give an educated guess on questions that overwhelm me. I have been thinking that skipping may be the best way to go.

Thanks for inquiry.

One cannot skip a question on the GMAT CAT. You must click on an answer and then you must click on "answer confirm." So the person whom you read was either misinformed or taking a paper-based test, which would be very unreliable to begin with.

Hopefully helpful,

Skipping a question probably means guessing after no more than 10-15 seconds
