Which LSAT Administration is the Hardest?
Over the years, we have heard a number of pervasive myths discussed as people attempt to compare one particular LSAT administration to another, perhaps the most common of which is that one test is typically easier, harder, or somehow different than the others.
The truth is that every LSAT is more or less the same. That's true in terms of content, structure, and difficulty with respect to final score.
Now, granted, some tests do prove to be "harder" than others, but there are three things to keep in mind:
"Hard" is remarkably relative, and as a general rule won't necessarily apply to you or any other individual test taker, so it's a misnomer from the outset;
There's no consistency regarding when a slightly more challenging exam might appear, so no reason to think of any specific administration (February versus October, say) as being predictably tough;
"Harder" exams have looser conversion scales, so it takes fewer questions answered correctly to attain a particular score.
That last one is of particular importance. Essentially what happens is that if a test is found to be somewhat more challenging for the average test taker (average number of questions answered correctly is slightly lower than normal), the test makers adjust the scoring scale in your favor: fewer correct needed for a given score. This allows them to keep the score percentages consistent across exams, even if the difficulty varies somewhat. So let's imagine for a second that the October test is actually harder than the others. What would happen? They'd award you a higher score for X number correct than they would for that same number correct on an easier test. In short: they use the scale to negate any subtle changes in overall difficulty.
