Hi LiquidFireAK,
Of your 4 RC passages on Test Day, you'll likely see at least 1 prompt that you would consider "long." Of course, there's some "bias" in this point because what you might consider "long", others (including the GMAT writers) might actually consider "medium." The truth is that the length of the prompt can sometimes mean nothing in terms of its difficulty. For example, some of the wordiest questions that you'll see in the Quant section are actually quite easy - you're being tested on your ability to stay organized and take notes. The same applies to questions in the Verbal section. The process for dealing with RC passages and their questions is essentially the same, regardless of the length of the prompt, the content, etc., so don't get too distracted by the length. You'll likely need a bit more time to read and take notes, but that's not really a big deal.
GMAT assassins aren't born, they're made,
