Hi peteS,
While it's not too common, Test Takers CAN see 3 RC passages on Test Day (especially if you're performing well at certain points during the Verbal section). It's interesting that you're attributing your pacing problem to RC - unless you pay for the Enhanced Score Report, we won't have any proof that that's actually the case (you might have had bigger pacing issues in SC and CR). There are also other factors that could have influenced your pacing/endurance/fatigue on Test Day besides those 3 RC passages.
1) How did you score overall (and what was your Quant Scaled Score)?
2) What was your goal score?
3) Are you planning to retake the GMAT?
GMAT assassins aren't born, they're made,
