Digital SAT Prep

SAT prep that teaches you how to think

Most prep drills content. Lotus drills the cognitive skills that separate a 1200 from a 1500 — trap recognition, answer elimination, pacing, and confidence calibration. Built around a Cognitive Autopsy after every wrong answer.

No credit card required. 10 free questions per day.

Study Plan Generator

A 4-phase plan, rebuilt around your test date

You enter your SAT date, target score, study days per week, and minutes per session. Lotus generates a Foundation → Targeted → Review → Final Stretch plan with daily tasks, question targets, and automatic rest days.

  • Daily task cards: practice, review, full-length tests, rest
  • Phase progress bars so you always know where you stand
  • Email reminders when you miss a study day (opt-in)

Cognitive Autopsy

Every wrong answer becomes a coaching moment

When you miss a question in Tutor mode, Lotus runs a Cognitive Autopsy: which trap caught you (out of 10 decoded types), where your reasoning diverged, and the specific micro-skill that would have caught it. Makes expert cognition visible and learnable.

  • Named trap labels: Almost Right, Extreme, Out of Scope, Partial Read, and 6 more
  • Reasoning replay showing how a high scorer actually solves it
  • Countermeasure skill prescribed per trap (e.g., Half-Right Detector, Extreme Filter)

Coach Claude

A live AI tutor that knows your trap profile

After any question, correct or not, open a streaming chat with Coach Claude. It's trained on your personal trap history and the question's full taxonomy — so instead of generic explanations, you get advice tuned to how you think.

  • Quick-prompt buttons: best strategy, avoid this trap, show the reasoning replay
  • Up to 10 exchanges per question with streaming responses
  • Deflects personal topics — strictly SAT strategy, strictly professional

Question Bank

1,000+ Digital SAT questions tagged on 8 dimensions

Every question is deeply analyzed: section, domain, question type, cognitive load, trap type, strategy skills, reasoning format, and reasoning order. That's why Lotus can show you not just what you got wrong, but why — and what skill to drill next.

  • 14 question types across Reading, Writing, and Math
  • Grid-in support for Math student-produced responses
  • 10 convention sub-types for grammar precision

Adaptive Full-Length Tests

3 adaptive tests that mirror the real Digital SAT

Module 1 mixes difficulty; Module 2 routes hard or standard based on a 70% performance threshold — the actual routing logic College Board uses. You see scaled scoring (400–1600 total, 200–800 per section) and a per-module difficulty breakdown.

  • True two-module adaptive engine, not a fake simulation
  • Scaled score reports with section splits
  • Automatic review of missed and low-confidence questions

5-Dimension Progress

Not just '% correct by subject'

Five independent axes of insight: which traps catch you most, how you score by question type, how well you eliminate under pressure, how your reasoning chains hold together, and whether your confidence tracks your actual accuracy.

  • Trap susceptibility lollipop chart across 17 decoded traps
  • Question-type heatmap with green/amber/red grading
  • Elimination profiler catching 'fast & wrong' and 'slow & right' patterns

How to prep for the Digital SAT in 4 steps

  1. 1

    Take a baseline full-length test

    See your scaled score and which traps caught you most. Ten minutes of setup saves weeks of untargeted drilling.

  2. 2

    Set your target + test date

    Lotus generates a 4-phase plan with daily tasks scaled to how many weeks you have until test day.

  3. 3

    Drill with Cognitive Autopsy feedback

    Every wrong answer becomes a coaching moment. Coach Claude is a click away when you want to go deeper.

  4. 4

    Full tests + 5D progress checks

    Take a full-length every 2–3 weeks. Watch your trap profile collapse and your question-type heatmap go green.

Frequently asked questions

What is different about the Digital SAT?

It's shorter (2h 14min), adaptive (Module 1 routes you to a hard or standard Module 2), and lets you use Desmos across the entire Math section. Every full-length test on Lotus mirrors that structure.

How long should I study on Lotus?

Most students see meaningful movement in 8–12 weeks at 4–5 sessions per week. The study plan generator tailors intensity to your test date — aggressive if you're 4 weeks out, steady if you're 12 weeks out.

How is Lotus different from Khan Academy or Bluebook?

Khan teaches content. Bluebook drills questions. Lotus teaches the cognitive skills that separate high scorers — trap recognition, elimination discipline, and pacing — with a Cognitive Autopsy after every wrong answer and an AI tutor that knows your personal trap profile.

How many SAT questions do you have?

Over 1,000 Digital SAT–aligned questions today, growing weekly. Every question is tagged across 8 dimensions so your practice actually targets your weaknesses.

Is there a score guarantee?

Yes — if you follow your generated study plan and complete the full-length tests on schedule and don't see a 200+ point lift, we refund your subscription. Details on the pricing page.

Does Lotus include the PSAT?

Yes — Core and Pro tiers include both SAT and PSAT access, since they share sections and question taxonomy. Students use Lotus for PSAT in fall and roll directly into SAT prep.
