Two mental-math shortcuts
What is 29^2? What is the square root of 9,801?
Work from round numbers rather than multiplying longhand.
(30 - 1)² = 900 - 60 + 1 = 841.
99² = (100 - 1)² = 10,000 - 200 + 1 = 9,801.
29² = 841 and √9,801 = 99.

5 firm-labeled workbook prompts. Three fully worked examples are open below; use the reveal drill for the rest. No signup.
Use the workbook by stage:
Record one answer in 90 seconds and lead with the conclusion.
Pair one credit or markets question with one core technical question.
Run three mixed questions, then repeat the least clear answer.
Read the setup, work the steps, then say the answer cleanly.

Given EV component values - how does using cash to pay dividends impact EV?
Cash and equity value fall together in the enterprise-value bridge.
EV = equity value + debt - cash.
Paying a dividend reduces cash and equity value by the same dollar amount.
The lower equity value and lower cash offset each other, so enterprise value does not change.
What is the ending value of a DCF if you used levered FCF instead of unlevered FCF?
The cash-flow definition and discount rate must match.
Levered free cash flow is after interest and belongs to equity holders.
Discount levered FCF at the cost of equity.
The DCF produces equity value. Discounting levered FCF at WACC mixes claims and does not produce a meaningful enterprise value.
The remaining prompts stay closed until you commit to an answer. Round labels come from the workbook source, not a fixed interview script.
Increase -> spend less (borrowing costs more, consumers pay down balances). Decrease -> spend more (cheaper credit). This is the transmission of monetary policy to consumption.
It falls: higher ratings signal lower default risk, so lenders demand narrower credit spreads over Treasuries (and more investors can buy it, e.g., investment-grade mandates), lowering the yield on new debt and WACC.
