The LSAT experimental section: why you cannot spot it and should not try

Every LSAT includes a section that does not count. It is the single most speculated-about feature of the test, and the speculation is a trap with an unusually severe downside.

What it is

This is ordinary test construction rather than anything sinister. Before a question can count toward anyone's score it has to be tried on real test takers under real conditions, so that LSAC knows how it behaves. The unscored section is where that happens.

It also explains why the section is indistinguishable by design. Questions tried out under relaxed conditions would produce useless data, so the whole point is that you treat it exactly like a scored one.

Why the spotting tricks fail

The usual theories are that the repeated section type is the experimental one, or that the unusually hard section is, or that it is always in a particular position. Each of them fails for the same underlying reason: you have exactly one data point.

• Two Logical Reasoning sections are scored anyway, so seeing a third does not tell you which of the three is the extra one.
• "It felt harder" is not evidence. Difficulty is subjective, sections vary, and a section you found hard may simply be the one that caught your weakness.
• Position theories require knowing the pattern for your form, which you do not.

What guessing wrong costs

This is the part that makes the whole exercise a bad bet. If you decide mid-test that a section does not count and coast through it, and you are wrong, you have thrown away a scored section. There is no recovery from that and no way to know until scores are released.

Weigh the two outcomes. Guessing right saves you some effort on a section that was never going to matter. Guessing wrong costs you the test. Even at even odds that is a terrible trade, and the odds are not even.

There is also a subtler cost. The mental effort of running a detection theory during a timed section is effort not spent on the questions, and the suspicion itself degrades your focus in a way that shows up in the sections that do count.

The correct approach

Treat all four sections as scored, because as far as you can know, they are. If it turns out one did not count, you have lost nothing — you simply did your best work on a section that happened not to matter, which is exactly what you would do again.

The useful preparation is stamina. Four sections is what you have to sustain regardless of how many are scored, so practice at that length rather than at three.
