LSAT Unscored Variable Section

Every officially administered LSAT contains four scored sections (35 minutes each) as well as an extra unscored "variable" section. It is designed to pre-test questions that could be potentially used as a scored section on a future LSAT exam. According to LSAC, this particular portion of the exam is used to "pretest new test items and to preequate new test forms." It is a way for the test makers to determine both the validity and difficulty of the questions before they are officially put into a real test.

This section has no direct impact on your LSAT score. Statistical analyses are implemented on your answers, which ultimately determines a larger, macro picture on the difficulty as well as the soundness of each question. With this awareness of the test scoring scales can be determined prior to a test being administered and the LSAC can determine how many incorrect answers a 170-level scorer would have, a 160-scorer would have, et cetera.

The experimental section looks like one of the other sections, so it is impossible to determine which section it is. Everyone who takes the test that day also has different sections altogether (the order of section topic varies) so there are different test orders and forms. This prevents test takers from making a collective informed score prediction/cancellation afterwards. The scored portion of the LSAT always consists of: Logic Games portion, Reading Comprehension section, and two Logical Reasoning sections. Thus, if you see two Logic Games sections on the test, then the experimental section is one of them.

In conclusion, you must consider each section as though it could be experimental, yet do your best to ensure that you perform your best from the beginning to end. Even if some test takers claim to be able to sense which section is the variable, it's not a definite, so treating all sections with equal due diligence is the best strategy come test day.
