I mean I don’t usually guess... I think for that test I was able to scan the game and Qs really quick and just tried to use intuition. So maybe not a complete blind guess.
You can look up PowerScore’s skipping strategy based on answer choice appearances overall, per section, and in the last 5 per section to give you a good starting point.
It’s important to note that this is only good for a completely blind guess, as in you have no idea or inclination as to a direction for the particular question, or any AC that seems weak/step nag, nor has any particular answer choice been unusually prevalent or scarce.
If you’re regularly guessing, it might be might worthwhile to address why instead.
