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. It is a way for the test makers to determine both the validity and difficulty of the games before they are officially put into a real test.

The experimental section looks like one of the the other sections so it is impossible to determine which section it is. Everyone who takes the test that day also have different sections altogether (the order of section topic varies) so there are different test orders/test forms; it prevents test takers from making a collective informed score prediction/cancellation afterwards. The scored portion of the LSAT always consists of 1 Logic Games section, 1 Reading Comprehension section, and 2 Logical Reasoning sections. Thus, if you see two Logic Games sections on the test, then the experimental section is one of them.

The conclusion is that 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 is not true. There is no way of knowing specifically while you are taking the LSAT which section is the variable.
