Finance
Time value, first. Everything else, later.
the shape of this subject
Finance is time-value reasoning wearing many hats. Brainback keeps you writing the cash-flow timeline before you discount anything.
Because finance rewards the students who do the reps — and punishes the ones who outsource them.
- discipline
- Business
- typical weekly load
- cases + memos · 4-6 hours
- covered on plan
- all plans (free forever)
Every finance concept Brainback covers.
Add Finance as a Learn subject and every problem in these areas routes to the Socratic tutor — attempt-first, hint-laddered, output-guarded.
What one turn in finance actually looks like.
Attempt → correction → guiding question. No answer. Ever. Verbatim from a beta session.
NPV = Σ CF_t / (1+r)^t; I used WACC as r…
What's your discount rate? Justify it.
no answer · one guiding question · your next move
How real attempts start. How Brainback nudges.
- NPV = Σ CF_t / (1+r)^t; I used WACC as r…
- What's your discount rate? Justify it.
the anti-pattern
What finance looks like when the AI does the thinking.
Answer machines make finance look like a solved problem. It isn't. The exam room reveals whose reasoning was built and whose was rented.
- M1Treating a case as a checklist of frameworks.
- M2Reaching for MECE structure before understanding the actual problem.
- M3Skipping the 'so what' — good analysis with no recommendation.
- M4Anchoring on the first number without stress-testing it.
the recall card
What a spaced-repetition card looks like in finance.
Every wrong attempt and low-scored explain-back becomes a card. SM-2 schedules them — the tricky ones come back tomorrow, the solid ones drift out to next week, then next month.
Recall the core concept in your own words. Then apply it to a fresh example under 2 minutes.
