A finance curriculum where you don't watch lessons — you make the call. Every decision Brier-scored. 46 courses. Free forever.
Not judgment. Not calibration. You can memorize every ratio and still be useless when someone says: should we build this position?
Every module ends with a real scenario. You make the call before you know the outcome. Then you're Brier-scored on how well your confidence matched your accuracy.
Every call you make updates your rating. Calibrated decisions move it up. Overconfident calls move it down. Watch it compound over a semester.
From behavioral economics to bond math to quantitative methods. A structured sequence where each tier unlocks the next. Not a pile of videos — a curriculum.
TopLine is a full learning environment. Scenarios, interview prep, simulations, market games, and a live rating that tracks your calibration over time.
This was built by a student who spent a year piecing together a finance education from fragments. No school had it. No platform had it. So it got built — and made free, because that was the original problem.
Live scenario from the Core curriculum. Read the data, make your call, and see exactly how your confidence is scored.
You are a junior analyst. A senior associate drops a single-name on your desk: a large financial firm with a stellar reputation, record profits, and a stock near all-time highs. She wants to know if the desk should build a long position.
| Company A — Selected Figures | |
| Assets | $400B |
| Equity | $12B |
| Leverage (assets / equity) | ~33× |
| Funding type | Short-term overnight repo |
| Liquidity cushion | ~3 weeks |
| Reported earnings | Record high, 3 consecutive years |
Based only on what you see above, what position do you recommend?
The correct read was Sell / short. 33× leverage on overnight repo with a 3-week liquidity cushion is catastrophically fragile regardless of reported earnings. The firm collapsed within months.
