<p>Like for example Sprng vs. Summer vs. Fall etc.,? Does all the exams have same level of difficulty?</p>
<p>i don't think the difficulty level should change...</p>
<p>it's a myth. I believe all the questions are random, but some test dates may prove to be easier for the test taker.</p>
<p>Using the curves of the past few years of SATs, I really can't see any correlation between difficulty and time of year (I'm doing this informally by just looking at a particular month and making sure that the tests for that month have been roughly equally easy, medium, and hard).</p>
<p>The tests really do vary in difficulty, though, at least a little. Except from a psychological viewpoint, none of this really matters: the curve that converts from raw to cooked scores is there specifically to adjust for the difficulty level of the test...</p>
