# Think Clearly Prep > Think Clearly Prep is an LSAT learning platform: an online exam simulator that works like the digital test and explains every answer choice, a symptom-by-symptom troubleshooter, free guides to the current format, curated video lessons, and the study guide "Think Clearly: A Study Guide for the LSAT, 2026–2027 Edition". The diagnostic, troubleshooter, video lessons and guides are free; full access to the practice library is a one-time $39 for 12 months. Study guide status: Coming soon on Amazon; its price has not been announced. Key facts (last reviewed October 2026): - The online practice library has 425 original multiple-choice questions with every answer choice explained: a 20-question diagnostic, 3 full-length practice tests, 171 timed drill questions (nine Logical Reasoning family blocks and three Reading Comprehension sections) and 3 timed Argumentative Writing prompts. - The study guide teaches concepts, strategy and troubleshooting rather than printing practice sets: 352 pages, 33 chapters, 60 worked examples, 30 diagrams and 3 writing prompts. Every chapter ends with a QR code to the matching practice or troubleshooting page on this site. - It covers the LSAT format in use since August 2024: two scored Logical Reasoning sections, one scored Reading Comprehension section, one unscored variable section, and Argumentative Writing. There are no Logic Games. LSAC has announced that from the August 2027 test the unscored questions move inside the three scored sections (Reading Comprehension first, 52 minutes; then two 45-minute Logical Reasoning sections), with 77 scored questions as now. - Each practice test has 78 questions in the scored-section pattern (Logical Reasoning 25, Reading Comprehension 27, Logical Reasoning 26) plus a writing prompt with three or four perspectives. - Every wrong answer is explained with a named trap (for example Too strong, Reversed, Out of scope), and every Logical Reasoning question is tagged with one of the nine official question families. - The simulator mirrors the digital test's functional layout: two panes, A-E answer rows, flag, answer elimination, highlighter, review grid, hideable 35-minute timer, numbered navigation grouped by passage, passage-only view, find in text, font/contrast/zoom settings, and Argumentative Writing in two timed phases (15-minute prewriting, 35-minute essay). It adds per-choice explanations, results by family and difficulty, blind review and an error log. It reports raw scores, not a 120-180 scaled score. - Free video lessons: 40 YouTube lessons from independent teachers and prep companies, sorted by the same families and tasks as the practice, with our own titles and summaries. Think Clearly Prep is not affiliated with their creators. - Access: the diagnostic, the troubleshooter, the video lessons and the guides are free for everyone, with no account. Full access is one payment of $39 for 12 months, not a subscription, and includes the full tests, the drills, the writing prompts and 100 AI coach requests; 500 more coach requests cost $10. Owners of the study guide verify their copy by answering a question about its chapter headings, and a book-owner price applies. Accounts are a username and password, with no email address; practice progress is stored in the reader's browser. There are no ads. - The AI coach answers questions about an item the student has already answered, grounded in that item's answer key and written explanations. - All questions, passages and prompts are original; none are official LSAT material. LSAT® is a registered trademark of the Law School Admission Council, which is not affiliated with and does not endorse this site or book. - Quality process: practice-test questions are solved blind, without the key, before release; questions with a second defensible answer are rewritten; answer keys are checked so the credited choice is not given away by its length. Difficulty Levels 1-5, the family mix and the within-section difficulty curve are modeled on the score report of an official practice test. ## Guides - [Free LSAT practice with explanations](https://thinkclearlyprep.com/lsat-practice-test/): Try original Logical Reasoning and Reading Comprehension questions with explanations, then open the free 20-question diagnostic.

Links last checked 2026-10-27. - [Conclusions and Disputes](https://thinkclearlyprep.com/lessons/#conclusions-and-disputes): Logical Reasoning; 2 videos, checked 2026-10-27. Questions that ask what an argument is trying to prove, or what two speakers disagree or agree about. Finding the conclusion is the first step on almost every Logical Reasoning question, so start here. - [Assumptions](https://thinkclearlyprep.com/lessons/#assumptions): Logical Reasoning; 2 videos, checked 2026-10-27. Necessary assumption questions ask what an argument depends on; sufficient assumption questions ask what would make its conclusion follow. Both start with the gap between the evidence and the conclusion. - [Strengthen or Weaken](https://thinkclearlyprep.com/lessons/#strengthen-or-weaken): Logical Reasoning; 2 videos, checked 2026-10-27. Pick the answer that makes an argument more or less convincing, or the question whose answer would help you judge it. The right answer only has to move the argument, not prove or destroy it. - [Flaws](https://thinkclearlyprep.com/lessons/#flaws): Logical Reasoning; 2 videos, checked 2026-10-27. Describe what is wrong with the reasoning. Flaw questions are the most common Logical Reasoning family, and the same errors come back again and again. - [Matching Flaws](https://thinkclearlyprep.com/lessons/#matching-flaws): Logical Reasoning; 2 videos, checked 2026-10-27. Find the answer whose argument makes the same mistake as the stimulus. Name the flaw in the stimulus before you read the answers. - [Matching Structure and Principles](https://thinkclearlyprep.com/lessons/#matching-structure-and-principles): Logical Reasoning; 2 videos, checked 2026-10-27. Match the pattern of an argument, or apply a general rule to a specific case. Describe the structure or principle in plain, abstract terms before you compare answers. - [Deductions and Inference](https://thinkclearlyprep.com/lessons/#deductions-and-inference): Logical Reasoning; 2 videos, checked 2026-10-27. Decide what must be true, or what is most strongly supported, using only the statements you are given. The right answer stays inside what the facts allow. - [Explain or Resolve](https://thinkclearlyprep.com/lessons/#explain-or-resolve): Logical Reasoning; 2 videos, checked 2026-10-27. Two facts seem to conflict, and the right answer shows how both can be true. Keep both facts in view and look for the difference that reconciles them. - [Techniques, Roles, and Principles](https://thinkclearlyprep.com/lessons/#techniques-roles-and-principles): Logical Reasoning; 2 videos, checked 2026-10-27. Describe how an argument works: the method it uses, the role a statement plays, or the principle behind it. These questions reward reading the structure rather than the topic. - [Conditional logic](https://thinkclearlyprep.com/lessons/#conditional-logic): Logical Reasoning; 2 videos, checked 2026-10-27. If, only if, unless, all and none: the language of rules. Conditional reasoning runs through several Logical Reasoning families, and confusing a rule with its reverse is one of the most fixable errors. - [Reading and mapping a passage](https://thinkclearlyprep.com/lessons/#rc-passage-mapping): Reading Comprehension; 2 videos, checked 2026-10-27. How to read a passage for its structure: the main point, the viewpoints, and what each paragraph does. A good first read makes every question faster. - [Main point questions](https://thinkclearlyprep.com/lessons/#rc-main-point): Reading Comprehension; 2 videos, checked 2026-10-27. Questions about a passage's main point or primary purpose. The right answer covers the whole passage, not just one paragraph. - [Detail and inference questions](https://thinkclearlyprep.com/lessons/#rc-detail-and-inference): Reading Comprehension; 2 videos, checked 2026-10-27. Detail questions ask what the passage says; inference questions ask what it implies. Both are answered from the text, so go back and check before you choose. - [Function questions](https://thinkclearlyprep.com/lessons/#rc-function): Reading Comprehension; 2 videos, checked 2026-10-27. Why does the author mention this, and how is the passage put together? Function questions ask about the job a word, example or paragraph does. - [Author attitude](https://thinkclearlyprep.com/lessons/#rc-author-attitude): Reading Comprehension; 2 videos, checked 2026-10-27. What does the author think, and how strongly? Attitude questions turn on word choice, so notice the difference between cautious approval and enthusiasm. - [Comparative passages](https://thinkclearlyprep.com/lessons/#rc-comparative-passages): Reading Comprehension; 2 videos, checked 2026-10-27. A Reading Comprehension set may use two shorter passages instead of one long one. The questions ask how the passages relate, where they agree and where they part ways. - [Timing and pacing](https://thinkclearlyprep.com/lessons/#timing): Method; 2 videos, checked 2026-10-27. Each section gives you 35 minutes for roughly 25 to 27 questions. These lessons cover pacing, flagging a hard question and moving on, and reaching the last Reading Comprehension passage. - [Blind review and the study cycle](https://thinkclearlyprep.com/lessons/#blind-review): Method; 2 videos, checked 2026-10-27. Blind review means re-answering the questions you were unsure of, untimed and before you check the key. Paired with an error log, it turns each practice test into a lesson. - [Argumentative Writing](https://thinkclearlyprep.com/lessons/#argumentative-writing): Writing; 2 videos, checked 2026-10-27. The writing task gives you 15 minutes of prewriting analysis and 35 minutes to write an essay that takes a position on a debatable issue. It is unscored, but it is required and law schools can read it. - [Format, scores and test day](https://thinkclearlyprep.com/lessons/#lsat-format): The test; 2 videos, checked 2026-10-27. What is on the test now, how the 120 to 180 score works, and what test day looks like. Rules can change between testing cycles, so confirm the details for your own test in your LSAC account. ## Free tools - [All free tools](https://thinkclearlyprep.com/tools/): calculators for LSAT takers and law school applicants, built on published LSAC and ABA data.
