This is where the safety nets come down. No pretests, no warm-up analogies, no “guess before reading” — just the course, checking whether any of it stuck. Everything you need, the previous five lessons already taught you. Read each option twice; the trap is usually the one that’s 90% right.
How this exam works
This is a graded exam. Questions come one at a time. Once you submit an answer it is final — there is no going back, no second try, and a wrong answer simply fails that question. Your score stays hidden until the end, where you need 70% to pass. Read every option twice before you commit.
What are the four levers that define any loan?

When you’ve passed, here’s the whole course collapsed into one map — the shape of everything you can now reason about:
Big picture
Loans & Mortgages
- Loans & Mortgages
- Anatomy
- Principal · rate · term · payment
- Secured vs unsecured · collateral · lien
- A mortgage = big, long, amortizing, secured
- Amortization
- Interest on the balance, principal gets the rest
- Early payments mostly interest; split flips
- Total interest = M·n − P
- Cost of credit
- Fixed vs variable (ARM)
- Note rate vs APR vs APY
- Term trade-off · the monthly-payment trap
- Upfront money
- Down payment · LTV = loan / value
- 80% LTV → PMI (protects the lender)
- Closing costs · points · break-even
- When it changes
- Extra principal · prepayment penalties
- Refinancing · break-even · clock reset
- Default → foreclosure → deficiency · underwater
- Anatomy
You finished Loans & Mortgages
You can now read a loan from the inside: price the four levers, decode an amortization schedule, tell the note rate from the APR, weigh a 15-year against a 30-year, size a down payment against the PMI line, and run a refinance break-even — and you know exactly what default, foreclosure and negative equity mean. No loan document can bluff you now.
