LSAT prep, coached not shortcut.
The reasoning test that AI summaries can't fake.
The LSAT is the purest reasoning test in the standardized-testing world. It has no content — there's nothing to memorize, no formulas to recall, no facts to know. What it tests is your ability to hold an argument in working memory, identify its structure, and evaluate what would strengthen or weaken it, all under time pressure. That's it. That's the entire test.
This is why generic 'study harder' advice fails on the LSAT and why AI summaries make it worse. There is nothing to summarize. The skill is the reasoning act itself, and the only way to build it is to perform it — attempt after attempt, with feedback on what your reasoning specifically missed.
Brainback is the practice layer for that. Every LR question, every RC passage, every LG game (if you're on a games-still-included administration) runs through Learn mode with the attempt-gate on. You commit to an answer choice + a reason before you can see any feedback. The tutor then names the flaw class you're closest to, gives you one guiding question, and hands the argument back to you.
Over a 3-6 month cycle, the effect compounds. Beta cohort N=22 saw a median +6 point improvement — smaller than some prep programs promise, but honest and consistent across the cohort. Bigger improvements are possible with longer cycles; smaller ones happen when students skip the daily untimed drilling that Learn mode is built for.
What our LSAT beta cohort has measured.
What you’re actually facing on test day.
Total: ~3 hours (including experimental section). Below is every section, with its duration, question count, and scoring role.
| section | duration | questions | scoring |
|---|---|---|---|
| Logical Reasoning · Section 1 | 35 min | 24-26 | counts |
| Logical Reasoning · Section 2 | 35 min | 24-26 | counts |
| Reading Comprehension | 35 min | 26-28 | counts |
| Experimental (variable) | 35 min | varies | doesn't count |
| Writing sample (unscored) | 35 min | 1 prompt | reviewed by schools |
Scaled score 120–180. Median 152. T14 competitive: 168+. Full-ride threshold: 172+.
A week-by-week rhythm.
Rehearsable. Predictable. Adjustable for your calendar. Each week has one focus and one specific Brainback move.
| when | focus | brainback move |
|---|---|---|
| Month 1 | Fundamentals: LR question types + diagramming | One LR question type per week in Learn mode. Explain-back on the flaw class definitions. |
| Month 2 | Reading Comp technique + LR mixed practice | RC passages daily. Recall queue at 100+ cards on flaws and RC structures. |
| Month 3 | Timed sections | Timed sections 3x/week. Untimed error review daily. Brain score starts predicting scaled scores. |
| Month 4 | Full-length preptest weekly | Every Saturday: a full preptest. Every Sunday: Learn mode on every wrong answer. |
| Month 5 | Weakness kill + timing polish | Any question type with < 80% accuracy gets an extra 30 min daily. |
| Month 6 | Rest week + AAMC-equivalent official prep | One preptest early in the week. No new content. Recall + sleep dominate the last 5 days. |

What Learn mode actually does on an LSAT question.
A representative exchange: the problem, your attempt, the tutor’s response, your follow-up, the downstream card. Notice the tutor never solves.
LR: 'The mayor's proposed transit plan will reduce congestion because it will discourage private-car use. Therefore, the plan will succeed.' What flaw does this argument make?
It assumes discouraging cars will actually reduce congestion.
That's a real assumption in the argument, but it's not the FLAW being tested here. Look at the conclusion — 'the plan will succeed.' What does 'succeed' mean here? The premise talks about congestion reduction; the conclusion says success. Are those the same thing?
Oh — the argument conflates 'reducing congestion' with 'succeeding.' Success might mean adoption rates, budget, ridership, political viability. The premise only supports one narrow reading of success.
Three Brainback pieces matter most for LSAT.
All seven product surfaces are always on. For this exam specifically, these three carry the load. Each has its own dedicated page.
Every practice question in attempt-first mode. The tutor won't diagram it for you.
Explain the flaw class in your own words. Rubric-graded. Card generated for anything under 4/5.
Logical flaws + argument patterns retrieved on schedule, not the night before.
Three ways LSAT prep quietly fails.
And the specific Brainback mechanism that catches each one. This isn’t a promise — it’s what the workflow is designed to do.
Reading answer explanations without re-attempting the question
Every wrong answer becomes a Learn session; you attempt it a second time before the explanation appears.
Untimed practice never transitions to timed
The weekly cadence forces the transition on a schedule; you can't hide in untimed forever.
'I've done a million questions but my score isn't moving'
Volume without reasoning practice plateaus. Brain score decomposes accuracy by question type so you can see which specific type is holding you back.
Four anti-patterns to skip.
Common approaches that feel productive but produce nothing. Skipping these is worth as much as adding a technique.
because · You'll read them and take zero real preptests. Two prep books + PrepTest volumes is the sane stack.
because · If you're on a test date that still includes games, they're 25% of your score and the most learnable section. Learn them.
because · You'll score low, feel demoralized, and gain nothing. Preptests are a diagnostic once you're at the accuracy floor.
because · The LSAT rewards well-rested reasoning. Cramming produces the opposite.
What movement is realistic.
Realistic range: +5 to +10 points on scaled score across a 3-6 month cycle, from a baseline in the 148-158 range. Students starting in the 165+ range see smaller absolute gains (ceiling effects). Students starting under 145 typically need 6+ months and additional 1:1 tutoring; Brainback alone is less sufficient at that starting point.

Everything LSAT prep folks ask.
Does it work for Logic Games?▾
Yes — the tutor walks you through diagramming without producing the diagram. Since games were dropped from the LSAT for many test-takers, this is less critical than before, but still available for those still testing on games.
How does it compare to 7Sage / Blueprint?▾
Different products. Those are content + video-lecture heavy. Brainback is the practice + retrieval + recall layer around them. Use both.
Score improvement in beta?▾
Small cohort so far. Directional +6 points median across a 3-month cycle. We'll publish real numbers when N is meaningful.
What about the LSAT Writing sample?▾
Not scored, but reviewed by schools. Efficiency mode can help you draft the sample (it's not a graded exam once submitted); Learn mode isn't the right tool.
Should I take the test multiple times?▾
Modal successful test-taker takes it 1-2 times. More than 3 sittings starts to look like a red flag on your application. Brainback helps compress the number of sittings needed by getting your prep to the ceiling faster.
Does the tutor help with law-school applications?▾
Personal statement + application essays live in Efficiency mode (not Learn mode). See /for/law-school for the full 1L-through-bar workflow.
