CookSAT vs. Pursu: 1500+ Ceiling Grind or Diagnostic-Adaptive Prep?

CookSAT is a digital SAT platform built for students chasing 1500+, with 2,800+ questions, 1,000+ verified Desmos regression solutions, 200+ extreme-difficulty Module 2 problems, and a Discord community at $24/month (Plus, or $19/month on the 3-month plan) or $54/month (Premium with tutoring, or $44/month on the 3-month plan). Pursu is a $29.99/month digital SAT app with 3,000+ SAT archetype questions, a Score Map showing per-concept point predictions, and a continuous diagnostic that adapts to wherever your score is now. Choose CookSAT for the 1500+ ceiling grind; choose Pursu if you want a diagnostic that adapts to wherever your score is now.

CookSAT and Pursu are both modern digital SAT platforms — but they're optimizing for different students. CookSAT's marketing is unmistakable: "Everything you need to get a 1500+." It's built by top-1% scorers, for students chasing the ceiling. Pursu's product is built around a continuous diagnostic that works whether you're starting at 1100 or already at 1500.

That difference shows up everywhere — in the question difficulty mix, the tools each platform foregrounds, the pricing structure, and ultimately who each one is the right fit for.

Here's an honest breakdown of how the two compare in May 2026.

1. What CookSAT and Pursu Offer

At a glance:

CookSAT

• 2,800+ SAT questions across every Math and Reading & Writing domain.

• 4 full mock SATs on Plus; 12 full mock SATs on Premium — modeled after real SAT format.

• 1,000+ verified Desmos regression solutions — written-out walkthroughs of how to use Desmos on specific math problems.

• 200+ extreme-difficulty Module 2 questions — calibrated to the SAT's adaptive harder second module.

• 650+ SAT vocab words in 30+ study sets.

• Discord community access + interactive study community.

• Daily new questions released to subscribers.

• 2x weekly 1:1 tutoring with a top-1% SAT scorer — Premium tier only.

• Free question bank at cooksat.app (separate site) — try the question style before paying.

Pursu

• 3,000+ SAT archetype questions tagged by domain, difficulty, and the 236 atomic concepts on the digital SAT.

• Score Map with confidence range instead of a single score estimate (e.g., 1031–1095), plus per-section Math vs. R&W breakdowns.

• Top Opportunities — score-point predictions on weak concepts (e.g., "+34 pts Quick Win" on Transitions). One click drops into a 10-minute Speedrun on that concept.

• Speedrun Arena — 10-minute, 10-question rapid drills with XP and accuracy tracking.

• Unlimited Mock Exams — full-length simulations that follow the SAT's official adaptive difficulty, scored on the 1600 scale.

• 236 atomic concepts in the Concept Explorer, filterable by High Frequency (29), Hard Module (34), and Desmos (27).

• Sage AI coach — chat-based, references your actual Score Map.

• Self-reported Bluebook scores feed your Score Map — log your College Board Bluebook practice-test results in Pursu and they factor into the projection alongside Pursu's Mock and Practice signals.

The split: CookSAT optimizes for the hardest 5% of SAT questions; Pursu optimizes for the diagnostic loop that tells you which questions matter most for your specific score band.

2. What CookSAT Does Well

CookSAT's niche is sharp and well-executed. For students already scoring in the 1400s and trying to break 1500, it offers things most prep platforms don't.

✅ Extreme-difficulty Module 2 specialization

200+ questions explicitly tuned for the SAT's adaptive harder second module is a real differentiator. Most prep apps stop calibrating difficulty once you're past the "medium" band; CookSAT keeps going. If your bottleneck is the hardest 10% of questions, this is genuinely useful content.

✅ Large written Desmos solutions library

1,000+ verified solutions showing how to solve specific SAT math problems using Desmos regression and graphing techniques. CookSAT's approach is written walkthroughs of worked examples — distinct in volume of written explanations, though Pursu's Desmos Training (37 video lessons, including regression problems) covers the same techniques through a different format.

✅ Affordable entry pricing

Plus is $24/month at monthly pricing (or $19/month-equivalent on the 3-month plan) — one of the lower software entry points in the AI SAT prep category. (CookSAT's Premium tier at $54/month adds bundled human tutoring on top of the software; that's a separate service-purchase decision, not part of the software-vs-software comparison below.)

✅ Free question bank at cooksat.app

You can try CookSAT's question style for free at cooksat.app before committing to a subscription. Most competitors don't offer this.

For students already at 1450+ chasing the ceiling, with the discipline for self-directed difficulty drilling, CookSAT is one of the best-targeted products in the category.

3. What Pursu Does Well

Pursu doesn't try to specialize in any one score band. It tries to be the diagnostic layer that tells you what to study next, whatever band you're in.

✅ A diagnostic that runs continuously

Every Speedrun question and every Mock answer updates your Score Map in real time. There's no "take a diagnostic test, then study" flow — the diagnostic is the studying.

✅ Per-concept point predictions

The Top Opportunities module shows the actual score points each concept will gain you — "+34 pts Quick Win" on Transitions, for example. This is useful at any starting band because it tells you which 2-3 concepts to attack first.

✅ Bluebook scores feed your Score Map

Bluebook is College Board's official practice-test app — most serious SAT students are already taking those practice tests. Pursu lets you log your Bluebook results manually, and they factor into your Score Map projection alongside Pursu's own Mock and Practice signals. There's no API or partnership behind this — just a self-report field that means the work you're already doing on official sims adds to your signal inside Pursu.

✅ 3,000+ SAT archetype questions tuned to the digital test

Pursu's question bank is built around the recurring question shapes the digital SAT actually uses, tagged by domain, difficulty, and atomic concept. When the diagnostic flags a Quick Win concept, the Speedruns pull from this library — so practice on a weak concept drills the pattern that shows up on test day, not adjacent material.

✅ Works from any starting band

Pursu's 236 atomic concepts are filterable by High Frequency (29 — what shows up most), Hard Module (34 — for Module 2 prep), and Desmos (27 — Desmos-leverageable). The same product serves a 1100 student building fundamentals and a 1500 student grinding the hardest concepts.

For students who want a system that decides what to study next based on real performance data, Pursu is the more directive option.

What Makes Pursu Different (Beyond the Basics)

Beyond standard adaptive practice, Pursu has several features uncommon in the AI SAT prep category:

• Score Map with confidence range, not a point estimate. Pursu shows a band (e.g., "1031–1095") with the Score Sources module breaking down which signals — Bluebook tests, Pursu mock exams, Speedrun practice — contributed, weighted by trust and recency.
• Top Opportunities with point predictions. Each weak-area concept shows the actual score points you'd likely gain by mastering it (e.g., "+34 pts Quick Win" on Transitions). One click drops you into a 10-minute Speedrun on that exact concept.
• Bluebook scores feed your Score Map. Log your Bluebook practice-test results in Pursu and they factor into your projection alongside Pursu's Mock and Practice data — the official sims you're already taking just add to the signal.
• 236 atomic concepts with Hard Module filter. The Concept Explorer tags each concept by frequency and by whether it appears in the SAT's adaptive harder Module 2.

These aren't headline marketing claims — they're the architectural differences that show up after a few weeks of use.

4. Feature Comparison: CookSAT vs. Pursu

Side-by-side as of May 2026, based on each platform's public marketing materials:

5. Pricing: CookSAT vs. Pursu

Pricing as listed on each platform's marketing site, May 2026:

CookSAT

• Plus — $24/month monthly, or $19/month-equivalent on the 3-month plan. 2,800+ questions, 4 mock SATs, Desmos regression solutions, vocab sets, Discord, in-depth diagnostics, daily new questions.

• Premium (+ Tutoring) — $54/month monthly, or $44/month-equivalent on the 3-month plan. Everything in Plus, plus 12 mock SATs and 2x weekly 1:1 tutoring with a top-1% scorer.

• 3-month and yearly options available with 50% off annual.

Pursu

• Free tier — $0. Parts of the Pursu app are accessible without payment so you can try the product before subscribing.

• Pro plan — $29.99/month. Full Score Map, Top Opportunities, Speedrun Arena, unlimited adaptive Mock Exams, Concept Explorer (236 concepts), Desmos Training (37 lessons including regression problems), Vocab Training (1,000+ words), and Sage AI coach.

Apples-to-apples software comparison: CookSAT Plus is $24/month at monthly pricing (or $19/month-equivalent if you commit to the 3-month plan); Pursu is $29.99/month. Pursu is ~$6 more per month than CookSAT Plus at monthly rates. That gap buys Pursu's continuous diagnostic loop, 3,000+ archetype-tagged question library, and Top Opportunities point predictions — features CookSAT's question bank doesn't structurally provide at any tier. CookSAT Premium ($54/month monthly) adds bundled human tutoring services rather than software depth.

6. Who Should Pick CookSAT

Pick CookSAT if any of these describe you:

• You're already scoring 1450+. The 200+ extreme-difficulty Module 2 questions are calibrated for the highest band. If your current score is below 1400, you'll get more from a platform tuned to your range.

• You specifically want written Desmos walkthroughs at volume. CookSAT's 1,000+ written Desmos solutions library is sizeable for that format; Pursu covers the same regression techniques via a 37-lesson video Desmos Training mode if you prefer video over written.

• Your budget is tight at the entry tier. $24/month for Plus monthly (or $19/month on the 3-month plan) is competitive on price.

CookSAT's Premium tier ($54/month monthly, or $44/month on the 3-month plan) bundles 1:1 tutoring with a top-1% scorer on top of the software. If you specifically want a human tutor, that's a separate purchase decision — bundling it with SAT prep software vs. hiring directly. The software-vs-software comparison above is between CookSAT Plus and Pursu.

7. Who Should Pick Pursu

Pick Pursu if any of these describe you:

• You want a diagnostic that adapts to your current band. Pursu works whether you're starting at 1100 or 1500 — the Score Map and Top Opportunities recalibrate to your level.

• You want point-level visibility into what to study. Top Opportunities estimates the score points each concept will gain you — Quick Win badges, per-concept predictions, one-click into focused Speedruns.

• You want a question library tuned to SAT patterns. Pursu's 3,000+ archetype questions are tagged by domain, difficulty, and atomic concept — when the diagnostic flags a weak area, the Speedruns drill that exact pattern.

• You take Bluebook practice tests. Log your Bluebook scores in Pursu and they factor into your Score Map projection — the official sims you're already taking just add to the signal.

• You prefer a unified single-plan price. $29.99/month, no tier ladder, no upsells.

Final Verdict: 1500+ Ceiling or Score-Band-Adaptive Diagnostic?

CookSAT is built for the 1500+ ceiling. Pursu is built for the diagnostic that works at any score.

If you're already in CookSAT's target band — 1400-1500 grinding for the last 50-150 points — its extreme-difficulty specialization is genuinely well-targeted for that narrow case.

For everyone else — and that's most students — the bottleneck isn't a shortage of hard questions. It's not knowing which concepts to study next. Pursu's continuous diagnostic, 3,000+ archetype question library, and Top Opportunities point predictions are built around closing that specific gap, at any starting band.

CookSAT's Premium tier ($54/month monthly, or $44/month on the 3-month plan) bundles 1:1 tutoring on top of the software, which is a separate purchase decision — whether to buy software-plus-tutoring as a bundle, or pay for tutoring separately. The software comparison itself comes down to which platform's day-to-day study loop you'd rather be inside. If you already know you need to practice and the question is just what to practice, Pursu is the more focused tool.
