One engine, three stop points. The three lengths aren't three different quizzes — the 1-minute diag is the opening block of the 5-minute one, and the 5-minute run doubles as the routing stage of the 15-minute one. The 5-minute version tests one mid-level question in each of the five Logical Reasoning families (flaw, assumption, weaken, strengthen, inference) plus one adaptive follow-up. The 15-minute version then sends an easy/hard pair into your two weakest families — missing easy questions means shaky fundamentals, missing only hard ones means you break under difficulty, and those get different lessons — and finishes with a three-question Reading Comprehension passage.
Scoring is difficulty-weighted and honest about its limits. Hard questions move your skill read more than warm-ups. Skills are ranked by weighted accuracy times how load-bearing the skill is (a flaw gap blocks more of the test than a strengthen gap). A score estimate appears only on the 15-minute version and only as a range — a dozen questions can place you in a band, not on a point. Your per-question time is also measured: accurate-but-slow is its own diagnosis with its own lesson.
Every wrong answer is a named trap. Each question's wrong choices are tagged with the trap they set — out-of-scope, too-strong, opposite-direction, premise-restating, wrong-target. Which traps you fall for is often a better lesson signal than which questions you miss, and the 15-minute report calls yours out.
The lesson match is a curated map, not a guess. Each skill-and-level combination maps to a specific lesson in the 104-lesson course — verified, current, and watchable free. All questions are original Burton Method examples (real PrepTest questions are LSAC-licensed and can't be republished); everything runs in your browser and nothing is sent anywhere until you ask for your lesson.
Frequently asked questions
How accurate is a 1-minute or 5-minute diagnostic?
Honestly labeled: the 1-minute version is directional — a few smart questions about where you are plus one real Logical Reasoning question. The 5-minute version tests one question in each of the five LR skill families, which is enough to rank your skills against each other but not enough to predict a score. The 15-minute version adds harder follow-ups in your two weakest skills plus a Reading Comprehension passage, which is when a score range becomes defensible. More time, sharper read — but for someone brand new, 1 or 5 minutes is genuinely enough to know where to start.
Do I get a real score prediction?
Only the 15-minute version estimates a score, and it's always presented as a range, never a single number — roughly a dozen questions can place you in a band, not on a point. Shorter versions rank your skills instead, because pretending 6 questions can produce a 120-180 score would be junk precision. For a real scaled score, take a full timed PrepTest and run it through our score calculator.
How does the diagnostic pick my free lesson?
The course has 104 lessons organized by question type and skill. The diagnostic measures which of the five Logical Reasoning families (flaw, assumption, weaken, strengthen, inference) — plus Reading Comp in the 15-minute version — is costing you the most, and whether you're missing easy questions (fundamentals) or only hard ones (advanced technique). That maps to a specific lesson: miss easy flaw questions and you get Flaw: Basics; miss only hard ones and you get the advanced flaw lesson. Brand-new students get the LSAT Basics lesson, because drilling a weakness you don't have yet isn't teaching.
Are these real LSAT questions?
No — deliberately. Real PrepTest questions are licensed by LSAC and can't legally be republished on free sites. Every question here is an original Burton Method example written to mirror the exact logical structures the LSAT tests: causal gaps, sampling problems, necessary-versus-sufficient confusions, quantifier chains. The skills transfer completely, and you'll drill real PrepTest questions inside the course.
Can I take it more than once?
Yes. Your progress saves for the sitting, so a refresh won't lose your place, and after any report you can continue to a longer version without re-answering anything — the 1-minute diag is literally the first block of the 5-minute one, which is the routing stage of the 15-minute one. Finished all 15 minutes? Start over any time; the question bank is bigger than any single run.
What happens after the diagnostic?
Your report shows your skill breakdown, pacing, and (on the 15-minute version) a score range and the answer traps you fall for — all free, no account. If you want the lesson it recommends, drop your phone number and the full video lesson with interactive practice opens instantly; we text you the link so you can come back to it on any device for 30 days.
