For IB, AP, and university-prep schools

Adaptive exam prep your school can measure.

Jukuna calibrates every practice question to each student's measured level — and shows your teachers exactly who needs help, on which topic, before the exam. AP, IB, SAT, IELTS, and 7+ exam tracks on one platform.

Flat per-school pricing · Invoice billing — no credit card · FERPA, COPPA & APPI aligned

Built on the methods with the strongest evidence in learning science

Retrieval practice

Students are tested, not re-taught — the most replicated result in learning science.

Spaced review

Missed concepts resurface automatically on a forgetting-curve schedule.

Worked examples

Math scaffolds fade as mastery grows — support for novices, none for experts.

Adaptive difficulty

Every question lands just above measured mastery — never busywork.

  • Set homework in 60 seconds; timed mock exams with official paper presets
  • Set this week's unit — student practice follows your scheme of work

Exam tracksOne engine, every exam

International cohorts mix AP, IB, SAT, and English proficiency in one classroom. Jukuna runs them all — each student on their own track, every teacher on one dashboard.

Runs inside your curriculumNot beside it

Your syllabus, converted into exam readiness

Jukuna doesn't replace your scheme of work — it runs alongside it, turning the units you already teach into syllabus-aligned practice and a readiness number you can act on.

Your materials → question bank

Teachers upload PDFs; Jukuna builds a calibrated, teacher-reviewable question bank from your school's own curriculum.

Unit pacing

Teachers set this week's topics. Student practice follows the unit, while spaced review quietly keeps earlier units alive.

Homework in 60 seconds

Five assignment modes, deadlines, per-student extensions, and rubrics — set tonight's practice from this week's unit.

Fits your stack

Google Classroom sync, CSV roster import, per-term progress reports. Jukuna attaches to your LMS — it doesn't replace it.

How it adaptsPer student · Per sub-topic

Personalized by measurement , not by guesswork.

01

A baseline in minutes, not a placement exam

Students confirm approximate levels in about a minute (or take an optional diagnostic). No 50-question gauntlet on day one.

02

Every answer recalibrates

Jukuna tracks mastery per sub-topic — not per subject — and serves the next question just above each student's measured level.

03

Support fades as mastery grows

Novices get worked examples and step-by-step scaffolds; as a student's level rises, the scaffolding steps back. Personal, but never softer.

04

Teachers see it as one number

Level vs. exam target, topic coverage, and recent momentum roll up into a 0–100 readiness score — with the weak topics named underneath.

A note on honesty: we don't promise point gains, and we don't sort students into "learning styles." Jukuna is built on the practices that survive replication — retrieval, spacing, worked examples, and one-to-one adaptivity — and we show you the measurement instead of a marketing number.

Safety & complianceBuilt for school procurement

The part your DPO will read first.

FERPA, COPPA & APPI aligned

DPA & SLA available

Standard data-processing agreement and service-level agreement for school procurement reviews.

Supervised AI tutoring

AI conversations are logged; concerning messages are flagged for teacher review — never silently dropped.

No ads, no data sales

Schools pay a flat fee. Students are the users, never the product.

Exam-integrity aware

Practice is generated fresh per student and the tutor explains method — it doesn't do graded work for them.

FAQWhat school leaders ask us
Does Jukuna replace our LMS?

No. Jukuna is the practice layer — it attaches to what you run (Google Classroom sync, CSV import) and focuses on calibrated practice and exam readiness. Gradebooks and course content stay where they are.

How is it priced?

A flat monthly fee per school, sized by enrollment — not per-seat, so growing doesn't penalize you. Billing is by invoice (bank transfer / 請求書払い). See the pricing page for tiers.

Will it raise our students' scores?

We deliberately don't promise score gains — independent research shows generic test-prep marketing wildly overstates them. What we promise is measurable practice built on the methods with the strongest evidence (retrieval, spacing, adaptivity), and a readiness metric you can verify yourself.

What about students who use AI to cheat?

Practice questions are generated fresh per student at their level, so answers can't circulate. The AI tutor explains method and concept; teacher-assigned, graded work is timed and monitored through the assignment system.

Which languages does it support?

The interface and explanations run in English, Japanese, Spanish, Russian, and Simplified Chinese. Exam content stays authentic to each exam's language.

What data do you collect, and who owns it?

Practice activity and account data, processed for educational purposes only — no ads, no resale, FERPA & COPPA aligned. A DPA is available for your procurement review, and accounts are domain-gated to your school.
