PowerScore LSAT Bibles Review

The PowerScore LSAT Bibles cost $70 for Logical Reasoning and $60 for Reading Comprehension, or $120 if you buy the two together as the Duology. They are worth that if you want the most thorough treatment of a single LSAT section in print and you will genuinely work through 1,185 pages; they are not worth it if you want one book that covers everything quickly.

Two things about them changed in 2026 and almost nothing online reflects it yet. Every roundup still prices the Bibles at about $45 each, which is an earlier printing's number, and the arguments you will find in forum threads are about a three-book Trilogy that PowerScore no longer sells. Everything below was read on 15 September 2026 from PowerScore's own catalog and the two current product pages.

PowerScore LSAT Bibles Overview

The Bibles are two separate books, sold separately, that between them cover the whole scored LSAT. Both are by David M. Killoran and Jon M. Denning, who have written the series for over 25 years and co-host PowerScore's LSAT podcast.

The Logical Reasoning Bible is the big one: 700 pages across 22 chapters, ISBN 979-8-31770-663-0. It works through the section one question family at a time, with chapters on Must Be True, Weaken, Strengthen, Justify the Conclusion, Assumption, Resolve the Paradox, Flaw in the Reasoning, Parallel Reasoning and Principle questions, plus standalone chapters on conditional reasoning, cause and effect, formal logic, and numbers and percentages. It closes on section strategy and time management.

The Reading Comprehension Bible is 485 pages, ISBN 979-8-31770-665-4. It is built around VIEWSTAMP, PowerScore's system for what to track while you read a passage, and it covers passage structures, comparative reading passages, common passage themes and section management.

What comes with each book:

• Strategies for every concept and question type in that section.
• Official LSAT material with worked explanations. The Logical Reasoning Bible states over 110 official questions; the Reading Comprehension Bible promises official passages and questions from past tests without giving a count.
• Extensive drills to practise each strategy separately.
• Free access to PowerScore's online self-study platform.

Note what is not on that list any more. PowerScore's catalog carries no Logic Games Bible and no Bible Trilogy. Both are gone, and that is the single most useful fact about this product in 2026.

PowerScore LSAT Bibles Review For 2026

The Trilogy is gone, and the internet has not noticed

Search for a review of these books and most of what comes back argues about a third volume. PowerScore's own forum, the r/LSAT threads, the Facebook groups and the YouTube reviews all debate whether the Logic Games Bible is the best book of the three, or whether the Trilogy is a must-buy.

It is not a question any more. LSAC's types of LSAT questions page lists exactly two, Reading Comprehension and Logical Reasoning, since Analytical Reasoning was removed in August 2024. PowerScore responded by dropping the book: the current catalog sells the two Bibles, the two matching workbooks, and the bundles that combine them. Nothing else.

The practical warning is about the secondhand market. Old Trilogy sets and standalone Logic Games Bibles still circulate cheaply, and a cheap three-book set looks like better value than a $120 pair. It is not. You would be paying for a third of a system aimed at a section you will not sit. Our best LSAT prep books roundup covers the same trap across other publishers, and the Manhattan Prep 5 lb. Book is the clearest example of a book that was never revised after the change.

The new editions bundle an online platform, and that is what you are paying more for

Both 2026-2027 product pages carry the same bullet, and it is the real change in this release. Buying either book gives you free access to a PowerScore online self-study platform that includes weekly study plans keyed to how far you are from test day, explanations for thousands of official LSAT questions, video lessons taught by Killoran and Denning, official LSAT practice tests, and performance analytics.

That is a serious list, and it reframes the price. A book that comes with official practice tests is not competing with other books; it is competing with the subscription you would otherwise buy to get those tests. For context, LSAC's LawHub Advantage costs $124 a year, which is more than the Duology.

Every way PowerScore sells the 2026-2027 Bibles. Source: powerscore.com, read September 2026.

Be careful how much weight you put on it, though. PowerScore describes the platform in that one bullet and publishes no feature page setting out how many tests you get or how long access runs. Treat it as a real bonus that improves the deal, not as a documented substitute for a LawHub subscription, and do not build a study plan around access you have not confirmed after purchase.

Depth is the whole product, and depth costs weeks

Seven hundred pages on one section is the argument for and against these books in a single number. No other LSAT publisher gives Logical Reasoning that much room, and it shows in how the chapters are cut: conditional reasoning and formal logic get their own treatment rather than a sidebar, and each question family gets a full chapter instead of a page of tips.

That suits a specific student. If your diagnostic shows you missing a particular question type over and over, a chapter that spends thirty pages on it is exactly what you need, and our guide to Logical Reasoning tips explains why that section deserves most of your hours now that it drives two of the three scored sections.

It suits others badly. These are dense, methodical, system-heavy books. You are asked to learn PowerScore's vocabulary and diagramming conventions before the payoff arrives, and skimming gets you nothing. If you have eight weeks and you want to be walked through the test in plain language, the reading load here will beat you, and a shorter book will serve you better.

The honest structural limit is that neither book covers the test on its own. The Reading Comprehension Bible will not help your Logical Reasoning score and the Logical Reasoning Bible does not touch passages. Full coverage means both books, and that is the $120 decision rather than the $60 one.

Pricing

PowerScore sells the self-study line six ways, and the list price for each was read on 15 September 2026 from its Self-Study Books and Tools catalog.

Book orders ship free in the US and Canada, so the sticker is the total.

Read the bundle savings honestly: they are $10. The Duology saves $10 against $130 for the two books bought separately, and the Practice Pack saves $10 against buying the Duology and the Workbook Pack on their own. Buy the bundle because you want both books, not because the discount is doing any work.

Spread across a 12-week prep, the $120 Duology is about $40 a month. That is cheap next to any LSAT prep course, including PowerScore's own courses, and expensive next to every other book we review. The LSAT Trainer is $48.15 and covers both scored sections in one volume. The Loophole in LSAT Logical Reasoning is $43.99 and goes deeper than anyone on the section that matters most. A used Manhattan Prep 5 lb. Book starts at $34.99.

The Testing and Analytics package is the one line to think twice about. At $49 then $35 a month it is a subscription, and the Bibles already promise official practice tests through the free platform that comes with them. Buy the books first and find out what the included access actually gives you before you add a recurring charge on top.

Who The PowerScore LSAT Bibles Are Best For

• Students who have plateaued on one section and want the deepest available treatment of it rather than another general strategy book.
• Anyone whose Logical Reasoning accuracy is the score ceiling, since the LR Bible is the larger, stronger half of the pair and that section drives two of three scored sections.
• Methodical self-studiers who like a named system, will learn PowerScore's vocabulary, and have twelve weeks or more to work through 1,185 pages.
• Retakers who took a course, know the question types by name, and need a different and more rigorous explanation of the same material.

When You Might Look Elsewhere

• You want one book, not two. The LSAT Trainer teaches both scored sections in a single 400-page volume for $48.15, which is a third of the Duology. If you can only buy one book, buy that one.
• Logical Reasoning is the only problem. The Loophole in LSAT Logical Reasoning at $43.99 is the cheaper way to go deep on the section that matters most, and it is written for the test as it stands.
• You want exams, not instruction. The official LSAC PrepTests are previously administered tests, and no method book replaces them. If practice volume is what you are short of, start there.
• You need someone to ask. A 700-page book cannot answer a question when a chapter does not land. PowerScore's own LSAT courses put the same method in front of an instructor, and 7Sage is the cheaper structured alternative.

Final Verdict

The PowerScore Bibles have earned their reputation and the 2026-2027 editions deserve it more than the last ones did. Dropping the Logic Games Bible was the right call, the online platform bundled with each book is a genuine addition, and nothing else in LSAT print goes as deep on a single section. Our 4.2 rating reflects that, with the deductions taken for the price, the reading load, and the fact that PowerScore documents the included platform in one sentence and nowhere else.

Then plan the reading rather than opening chapter one and hoping. Our LSAT study plan generator will lay 1,185 pages against your test date, our free LSAT practice questions cover the days the books are not with you, and the LSAT hub has the rest of your options.

PowerScore LSAT Bibles FAQs

How much do the PowerScore LSAT Bibles cost?

On 15 September 2026 the Logical Reasoning Bible was $70 and the Reading Comprehension Bible was $60, with both together as the 2026-2027 Bible Duology at $120. Adding the two workbooks takes it to $210 as the Bible Practice Pack. Book orders ship free within the US and Canada.

Is there still a PowerScore LSAT Bible Trilogy?

No. PowerScore's self-study catalog now lists only the Logical Reasoning Bible, the Reading Comprehension Bible, their workbooks and the bundles of those. The Logic Games Bible was dropped after LSAC removed the Analytical Reasoning section in August 2024, so a secondhand Trilogy set includes a book covering a section that is no longer on the test.

Which PowerScore Bible should I buy first?

The Logical Reasoning Bible, unless your diagnostic says otherwise. Logical Reasoning is two of the three scored sections on the current LSAT, so the return on fixing it is roughly double, and at 700 pages the LR Bible is the more substantial of the two books.

Do the PowerScore Bibles include practice tests?

Not in the books themselves, but each one comes with free access to PowerScore's online self-study platform, which the product pages say includes official LSAT practice tests, explanations for thousands of official questions, author video lessons and performance analytics. PowerScore does not publish how many tests that covers or how long access lasts, so confirm both after you buy rather than assuming it replaces a LawHub subscription.

Are the PowerScore Bibles better than The LSAT Trainer?

They go deeper; the Trainer is better value. The Bibles give each scored section its own full-length book and a documented system for working through it, which suits a student stuck on one section. The LSAT Trainer covers both sections in one $48.15 volume and teaches how to read the test rather than how to classify it, which suits most first-time self-studiers better.
