the cakewalk passage was a cakewalk
The only easier passage I ever saw was the "Relict Behaviors" passage from the June 2005 prep test. That was the alleged 'science' passage on that test.
On the other hand, the only passage I saw in PrepTests that was as tough as groupthink was the one about Puerto Ricans speaking Spanish and English from one of the other practice tests. Groupthink was hell.
I actually think the internet passage was even easier. I did it in under five minutes. Unfortunately, because I went so fast I missed an easy question - the one about devious business practices. On the other hand, if I hadn't gone so fast, I would definitely have run out of time on the groupthink passage.
