Hi GMAT Experts,
I'm interested in knowing how the GMAT adaptive algorithm decides the difficulty of RC questions.In the case of quant and for that matter, SC and CR, the algorithm can easily pick a question corresponding to a particular ability level and throw that on the screen. However, in the case of an RC question,what is the measure of ability - the passage itself or the questions associated with it ? . To make my point clearer, suppose that I answer a series of questions correctly and the algorithm assesses me as a 680 level person at this point. Now, the algorithm wants to throw up an RC question. What will be the question be like - will it be a relatively hard passage or will it be an average passage with each question associated with the passage being harder than the previous one?
I'm asking because if at this point I get a passage which is hard in terms of content , there is a likelihood that I could answer all 4-5 questions associated with the passage wrong, which could hurt my score tremendously. However, in the other scenario, I might get the 1st 2 questions correct and the next 2 wrong and the probability of a reduction in score would be lower in this scenario.
