Browse by subject
Every course is audio-first, with a full written version and quizzes. Nothing you want? Type the topic and one gets written.
Anyone can generate a course. Staying right is the hard part.
A course is only worth having if you can trust it — so most of what we do is the checking.
Written from the sources
On fast-moving subjects, lessons are written against current sources at the time of writing — not a model's memory.
Re-checked after publishing
Courses on subjects that move are re-checked on a schedule — being right the day it ships isn't enough.
Read against the source
A document deep dive is checked passage by passage against the original — by machine, then by a person.
CERTIFICATION PREP
A closed loop that ends when you pass
Most cert prep apps stop at the score. We close the loop with personalized feedback — and adapt the next exam to your gaps.
Free diagnostic
~20 questions in ~60s. See where you stand against the official exam, domain by domain — no card needed.
Personalized gap analysis
Your wrong answers shape a study guide written for YOUR weakest domain — not a generic course chapter.
Targeted study
Read the gap guide, listen to the audio course on your commute, do a focused micro-quiz to lock it in.
Retake — adapted to YOUR gaps
Next mock over-weights the domains where you struggled. Loop continues until your readiness score crosses the pass mark.
