GMAT Strategy

I tried to search it online, couldn't find. Does a time spent on each question in GMAT affect the score?
If someone knows a thread or a link, where there is a detailed explanation of scoring methodology, I would appreciate it. I have some sites where they explain, thought maybe you guys know something better
Thanks

You're already facing a time constraint (i.e. finishing 37 questions in 75 mins). The amount of time you spend on each question does not count when calculating your total score. However, as mentioned at the beginning of the OG, not finishing on time means a severe score penalty.
