Question is above. Does the GRE run the same exam for 21 days and then switch questions? Is that why we can only take it every 21 days? Do we know what point in the month it changes?
No, it’s from a pool I think. The 21 days is a bit arbitrary, but I think it’s also meant to discouraged organised cheating.
Does that mean if two people took it on the same day, they wouldn’t get the same questions (or at least same first section questions)? Thank you!
Probably, hard to say.
