The reason I ask is because the numbers look skewed in the breakdown report of the last practice GMATPrep exam I took. Based off of the report, I got a 35 in RC from answering only 2 RC questions incorrectly and one of these questions shows to be of 700-level difficulty. How does that make sense? My SC scores and CR scores were a bit higher, and I had more answers incorrect in those sections.
It's probably due to the characteristics of those questions. For example, if those were very easy questions, or questions that are very good at differentiating between different ability levels, they could have had a big impact on your score.
