No. Model Defense assumes you already know how to build a basic DCF, LBO, or 3-statement model — from a class, an internship, or self-study. It doesn't re-teach construction; it exists entirely to close the defense gap. If you've never built a model before, start with a foundational course first.

We can't guarantee an offer — no honest program can. What we guarantee is preparation: if you complete every gate in your assigned tracks and don't feel ready for your superday by your interview date, we extend your access free until you do. Details are in the Terms & Conditions.

The full Assumption Challenge is 40 questions — 5 across each of the 8 tracks (DCF, LBO, M&A, 3-Statement, Assumption Defense, Excel Speed, Sensitivity, Case Study). It's self-paced, so take it in one sitting or come back to it — there's no clock running. Each track gets its own Critical/Sharpen/Maintain rating, so you can start with whichever track needs you most. There's also a short 4-question survey beforehand to capture your role, timeline, and experience.

No. Every diagnostic question, lesson, and defense drill is hand-built from real practitioner experience — not AI-generated or AI-graded. Written defenses are self-scored against a practitioner rubric, the same way you'd self-assess before a real interview.

One payment of $299 gets you everything: the diagnostic, your personalised study plan, all assigned lessons, the timed modeling test simulator, and lifetime access. No subscriptions, no upsells, no extra charges.

WSP and CFI teach you to build a model — and they do that well. But if you can already build one, you've already been taught construction. The gap isn't building; it's defending it live, the way an MD or interviewer actually grills you. This programme is built entirely around that gap: every lesson names the specific defense traps for that model type, shows you why the shallow answer sounds fine, and locks the next lesson until you prove you can defend the real one.

Every lesson follows the same sequence: the 5 traps for that topic (with follow-up boxes for the harder ones), a worked numeric example with real inputs, an interactive calculator you can adjust live, a numeric calculation check, and 3 written assumption defenses graded against a rubric. Each lesson also has a downloadable PDF cheat sheet and a fill-in-the-blank CSV template you keep. The last lesson in every track is a capstone mock that pulls the whole track together.
