Will GRE (with the shortened format since last year) have any passages that are more than 2 paragraphs? I just took two “old” sections of official GRE questions and did pretty well (+15/16) on Short & Medium passages but the one very long passage (3 paragraphs, last paragraph was quite gargantuan) I bombed. If the long passages aren’t going to be reflective of what will be on the GRE, then this limited sample is a good start.
They are mostly not, don’t worry. Long passages are super rare now, when you do the powerprep practice tests you’ll see that. I would just focus on getting really good at the short (4 question) passages.
