Leaving questions unanswered costs u more than guessing (atleast there is 20% probability of getting it right with a random guess)

I would work on timing if possible so u have enough time to make atleast a educated guess or better solving them.

Good luck!

I agree - your best option is not to find yourself in this situation in the first place! Work on your pacing so that you leave yourself at least 30 seconds per question so that you can try to make educated guesses. A 1/4 or 1/3 shot at getting a problem right is a lot better than 1/5.

Failing that, yes, it's better to guess and answer every question rather than leave them blank.

I’ve significantly improved my timing issue just by following the priceless advices I found in this website (from Jim, Ian, Ron and others). Recently I found this time-strategy originally suggested by mgross (760) that is helping me budget time and keep up with proper pacing during my prep/mock tests.
