If you're preparing to take the LSAT in 2025 or beyond, then you must have encountered a lot of talk about PrepTests. The numbered practice tests, like PT1 through PT94, and then suddenly jumping to PT101 and above. It might leave you wondering, “Wait, what happened to PT95 through PT100?” Or maybe you're asking yourself whether those older exams are even helpful now that the new LSAT format is in place. This guide is here to help clear things up.
We've made an explanation on how to use the old LSAT exam for your preparation in 2025. But now, we’ll walk through how the old test numbers relate to the new LSAT structure. You will learn how to make the most of all available PrepTests (even the old ones), and why this matters for your study strategy.
What is the New LSAT Format?
Starting with the August 2024 LSAT, the exam underwent a major structural change. One prominent change is that the Logic Games section, also known as Analytical Reasoning, has been entirely removed. You can read more about the changes in our article covering all you need to know about August 2024 LSAT changes. This shift marks a significant change in the way the exam is designed and how you should prepare.
The new LSAT format includes:
Two Logical Reasoning (LR) sections, both of which are scored.
One Reading Comprehension (RC) section, also scored.
One unscored section.
One Writing Sample, which is taken online and not scored.
This revision was initiated by LSAC to enhance fairness and accessibility for all test-takers. Although the format has changed, the tested skills, critical reasoning, argument evaluation, and reading comprehension, remain constant.

Why Are the PrepTest Numbers Jumping?
In response to the new LSAT format, LSAC has released 58 reorganized PrepTests (numbered PT101–PT158) that adhere to this new LSAT structure. These tests are available on LawHub and specifically designed for the new LSAT format. So, while PT95–PT100 remain unused, you now have a fresh set of practice tests aligned with the updated version of the exam.
Why Use Older Tests at All?
Many students question whether the older PrepTests (PT1 through PT94) are still valuable given the changes in the LSAT format. The answer? Absolutely!
Even though those older tests include a Logic Games section, which is no longer on the test, the Logical Reasoning and Reading Comprehension sections in those tests are still completely relevant and can be aligned with the current exam. Here’s why using the older tests still matters:
Consistent Logical Reasoning questions maintain a consistent structure and difficulty level over time. They are excellent for developing analytical thinking skills.
Reading Comprehension passages reflect the same style and timing you will see in the new test format.
Using these tests helps you build stamina and recognize patterns in question types and reasoning. In short, they are not a waste of time; you simply need to fine-tune your approach.
How to Adapt Old PrepTests for the New LSAT Format
You don’t need to toss the old exams. With slight adjustments, they can be made to fit the new LSAT format quite effectively. Here’s how to use the old LSAT format for 2025 and beyond:
Ignore the Logic Games section. Since it's no longer part of the test, focus on the other sections.
Utilize the Lawprep180 resource to navigate the old PrepTests to the new format.
Select two LR sections. Choose any two from different PrepTests to simulate the dual Logical Reasoning requirement.
Add one RC section. Pick a Reading Comprehension section from another test that you haven’t utilized already.
By following this method, you will create a customized practice test that mimics the new LSAT format. This approach increases your ability to improve accuracy, pacing, and endurance.
Inside the spreadsheet, you’ll discover:
Logical Reasoning sections that align well with the revised PrepTest numbers.
Reading Comprehension (RC) sections with their corresponding PrepTest numbers.
