The right hours, not more of them.
Most prep gives you more material than anyone could finish and leaves you to guess whether any of it is working. Solurana is built on the opposite idea. You work the problem first, spend your time on the part of the curriculum that drives the score, lock it in with active recall, and watch a readiness number track how close you are. Everything below is how that method is built — and the evidence it rests on.
Built on the science of how you actually learn
The method rests on the current evidence. Three findings have advanced most in recent years: attempt before instruction, schedule against your own forgetting, and practice as the exam presents it. Each governs a specific part of the product.
Deeper understanding starts with the attempt, not the lecture.
The evidence inverts the usual order. Attempting a problem before being taught the method, known as productive failure, produces measurably deeper conceptual understanding than instruction first — an effect a meta-analysis of more than fifty studies finds robust, and largest when the attempt is genuine. Every topic therefore opens with a real exam item, and the gap it surfaces is precisely what you are then taught.
Productive failure · Sinha & Kapur, 2021A defined share of the curriculum carries the score.
A disproportionate share of marks derives from a limited portion of the curriculum: the material weighted most heavily, and the errors candidates make most often. The study plan concentrates there, so an hour of focused work returns more than several spent reading end to end.
High-yield weightingReview timed to your forgetting, not a fixed interval.
Conventional flashcards applied one schedule to every learner. Current systems model an individual's memory from each response and resurface material immediately before it would be lost. That advance lets modern algorithms hold the same retention with twenty to thirty percent fewer reviews.
Adaptive spaced repetition · 2023Interleaved and timed, as the exam presents it.
Two findings reinforce one another. Desirable difficulty: practice that is harder to retrieve, timed and unaided, is retained longer and transfers more reliably. Interleaving: mixing topics rather than drilling one develops the discrimination the exam requires. The likely range of outcomes is simulated, not assumed.
Desirable difficulty + interleavingThe method, where you will use it
Three things turn that method into a course you study from. Each is built to mirror the real CFA® exam in format and difficulty, not to flatter you toward the test center.
An explanation for every choice
Every question breaks down all three choices: why the right answer is right, and why each trap is built to catch you under time pressure — sign flips, formula mix-ups, the right rule in the wrong place. You learn the concept, not the key, so it transfers to whatever the exam asks.
An adaptive plan around your gaps
The plan forms around where you lose points and adjusts as you go: more time on what needs work, less on what you have mastered. Missed ideas come back on schedule, so ten minutes on a train is a real study session.
Full-length mocks, kept sealed
Six mocks on a faithful replica of the test screen, kept sealed so every item is new to you on the day. A desirable difficulty by design — a score you can plan around, built to predict your result rather than inflate it.
Why there are no video lectures
A deliberate choice, not a gap. Watching someone else calculate feels like progress, but nothing is retrieved, so it falls apart the moment a real question demands recall. You solve first, then learn exactly what the gap exposed.
Your time goes where the score is: exam-style questions first, every choice explained, and interactive charts you drive yourself. Drag a yield, watch the price bend.
Prefer to learn by watching? What you are after is seeing a concept move — the two demos below do exactly that. Test the fit with the free mock.
Not videos. Live.
Every exhibit responds to you. Drag an input and the math recomputes in real time — the one thing a textbook, a lecture video, or a four-figure legacy course can never do.

Built by charterholders, Wall Street veterans, and learning scientists
People who have earned the charter, not a content vendor repackaging someone else's material. Every question is written from the official curriculum and signed off by a charterholder before it reaches you — so what you practice mirrors what the exam actually asks.
It runs on one conviction: most prep wastes your time. No thousand-page textbooks, no lecture hours you will never finish — only the work that moves your score and shows up on the real exam. If it does not do one of those, it does not ship.
