LSAT Companion

The LSAT, decoded · powered by CogmemAi

The LSAT is not a mystery. It's an algorithm.

We teach the deterministic rules behind every question, then use CogmemAi to remember every drill, every trap, and every weakness — coaching you through your specific gaps until they vanish.

Every wrong answer has a name.

Here's a real-style Logical Reasoning question. The four wrong choices aren't there by accident — each is engineered against a specific trap pattern. We teach you to recognize the trap before you fall for it.

Logical Reasoning · Weaken
In a recent survey of city residents, 72% reported feeling unsafe walking downtown after dark. Crime statistics, however, show that overall downtown crime has decreased by 18% over the past five years. Therefore, downtown residents' fear of crime is irrational.
Which of the following, if true, most weakens the argument above?
  • A Crime statistics in similar cities have also decreased over the same five-year period.
  • B The 18% overall decrease is driven entirely by property crime, while violent assaults downtown after dark have actually increased by 22%.
  • C Many city residents do not visit downtown after dark and so cannot personally judge how safe it is.
  • D The 72% figure is based on responses from a representative sample of 2,400 city residents.
  • E Several downtown nightlife venues have invested heavily in private security in the past two years.

How the algorithm sees it

Each wrong answer is a trap with a name.

B
B · Correct answer
Directly attacks the conclusion: the 18% drop hides that the relevant subset of crime — violent, downtown, after dark — got worse.
A
A · Out-of-scope comparison
"Similar cities" is a red herring. The argument is about these residents' fear of this city.
C
C · Reverses the relationship
Looks plausible but actually strengthens the argument — if they don't visit, their fear is even less grounded in personal experience.
D
D · Tempting irrelevance
Validates the survey, doesn't touch the conclusion. Sample-size details ≠ argument logic.
E
E · Half-right
Sounds related to safety, but a response to crime doesn't show the fear is rational. Wrong direction.

The memory moat

Other prep starts every session from zero. We remember.

Every drill, every trap you fell for, every type you mastered, every Sage tutor exchange — written to CogmemAi, our persistent memory infrastructure. The longer you study, the smarter the system gets about you specifically.

  • The drill engine never repeats your mistakes. If you missed a Necessary Assumption with a Half-Right trap last Tuesday, this Tuesday's queue will hunt that pattern again — and only that pattern.
  • Sage knows your full study history. Ask "why do I keep missing these?" and she pulls your last 50 attempts to answer specifically — not in generic prep-book platitudes.
  • Score predictions get more accurate over time. Each drill is a calibration data point. Two weeks in, your predicted score has narrowed from a 12-point band to a 4-point band.
Why this works

Most prep teaches you tricks. We teach you the underlying frame.

Every Logical Reasoning question is one of 13 types. Every flaw is one of 17 patterns. Every answer choice is engineered against a small set of trap families. Once you see the machine, you can't unsee it.

The Algorithm

13 LR types. 17 flaw families. 10 trap patterns. The canonical taxonomy used by every elite tutor — drilled until it's second-nature.

Powered by CogmemAi

Our memory engine remembers every drill, every trap you fell for, and every type you mastered — then queues exactly the questions you need next. Other prep starts every session from zero. We pick up where you left off.

How it works

Four steps. No textbooks. No memorization tricks.

Diagnose

A 12-question diagnostic surfaces your real weak spots — the LR types, RC moves, and trap families you keep falling for.

Learn the frame

Eight short, dense lessons walk you through the deterministic rules behind every question on the test.

Drill the gap

Every drill set is generated against your weakest moves — 50% gap-filler, 30% reinforcement, 15% mastery check, 5% surprise.

Score the climb

Real-time score prediction. Mastery percent per type. Trap-fall rates. The dashboard tells the truth — every day.

A note from the founder

I spent six months grinding LSAT questions before I realized something obvious: every question is one of a small number of patterns, every wrong answer is one of a small number of traps. The score went up the day I stopped treating each problem as a puzzle and started naming the move.

The other thing I wish I'd had: a system that remembered me. Generic prep starts each session from scratch. So I built CogmemAi — persistent memory infrastructure — and put it under everything here. Every drill you take, every trap you fall for, every type you master goes into a memory that's specifically yours. Sage uses it. The drill engine uses it. Your score prediction gets sharper because of it.

This product is the tool I wish I'd had — the algorithm written down, the drill engine that hunts your weak spots, and a memory that actually remembers you. If it doesn't add 5 points to your score, I'll refund you. That's not a marketing line; it's how the math works out for both of us.
