parprimer.com Observed source

Editorial interest 84/100 Selection signal · not a rating of the site

An interactive fixed-income course that moves from bond fundamentals through mortgage math, securitization, RMBS structures, and interest-rate hedging.

Landing page captured for the 2026-09-15 issue.

Field notes

The curriculum is arranged so that fixed-income foundations precede mortgage fundamentals, securitization, RMBS structures, and hedging. Its interactive examples include a prepayment sweep from 0 to 500 PSA and a month-by-month four-tranche sequential deal with a Z-bond. The page also exposes Progress, Exam, and Glossary destinations, suggesting a course workflow rather than a standalone explainer.
