Attempt first, then reverse-engineer
CFA Drill is built for people who already know how to read a textbook and still miss items under time. The failure mode is familiar: you open an explanation, nod along, and never force a choice. Reverse engineering here is not a shortcut. It is a sequence that keeps the key hidden until you have committed.
1. Commit to A, B, or C
A Level I stem is usually a small model: a cash-flow timing, a ratio definition, or an ethics fact pattern. If you skip the click, you skip the model. The app asks for a choice first so the later explanation has something to contradict. A wrong answer is useful; a skipped stem is not.
2. Grade the attempt, not your mood
After you choose, mark the item as learning, blindspot, or mastered. Mastered is not “I got lucky once.” It is a deliberate state after a correct attempt, or a pattern of correct repeats. Blindspots are items you quarantine on purpose—fragile ethics scenarios, signs on duration, inventory methods you keep swapping. The blind-spot pool is global so a weak topic cannot hide behind a subject filter.
3. Only then open the reverse panel
The reverse-engineering panel is written to work backwards from the keyed choice: which formula, which timing convention, which duty in the Code. Read it as a reconstruction of the trap, not as a second textbook. If the panel still feels opaque, leave the item in learning and come back after a night, not after rereading the same paragraph five times.
4. What free and Pro change
Free accounts get a fixed sample per subject from the current bank edition so you can test the workflow. Pro unlocks the full bank for the edition stamped at checkout and removes ads beside drill content. Later editions and other exam levels, if offered, are sold separately. See Refund & Purchase Policy.
5. What this is not
These notes and the app are original study materials from EonDigi Inc. They are not CFA Institute curriculum, mocks, or an endorsement. Nothing here is investment, legal, or career advice. Personal on-screen study only— Terms.
