IBFlash vs Multiple Expansion
Multiple Expansion is a free blog of deep LBO and PE-recruiting tutorials written by working IB/PE pros — great for analysts learning to model in Excel. But it's self-study only, PE-focused, and assumes you already work at a bank. IBFlash is built for pre-IB undergrads: AI-graded spoken mock interviews, adaptive flashcards, and all five tracks (IB, PE, VC, HF, Consulting), with a 7-day trial from $40/mo.

Where Multiple Expansion wins
- Completely free — zero cost to read every tutorial and download the Excel templates
- Written by working IB/PE professionals, so the LBO and paper-LBO walkthroughs are technically deep and credible
- Excellent, genuinely detailed LBO modeling content (paper LBO, Training LBO, dividend recaps, standalone models) you can build along with in Excel
- Strong PE recruiting-process context (headhunter dynamics, on-cycle timeline, modeling tests) from people who lived it
- No account, login, or commitment required — bookmark and reference any time
Where IBFlash wins
- AI-graded spoken mock interviews give real feedback on your verbal answers — Multiple Expansion can only tell you to practice alone with no scoring
- Adaptive weakness-engine flashcards target exactly what you keep missing, vs. a static blog you have to self-curate
- Built for pre-IB undergrads (19-22) from day one, not analysts already at a bank mid-recruiting
- Covers all five recruiting tracks — IB (core), PE, VC, HF, and Consulting — not just PE modeling
- 7-day trial lets you try the full product before paying; Starter is $40/mo
- Structured, guided prep path with progress tracking instead of dozens of loose articles you assemble yourself
FAQ
Is Multiple Expansion free?
Yes. As verified on their live site in June 2026, Multiple Expansion is a completely free educational blog — every LBO tutorial and Excel template is free, with no paid course, subscription, or premium tier. It's monetized only through a sponsor.
Is Multiple Expansion good for undergrads prepping for IB interviews?
Less so. Multiple Expansion explicitly targets current banking analysts recruiting for private equity, and assumes you already work at a bank. For a pre-IB undergrad, the technical depth is useful background but the framing, examples, and recruiting timeline are aimed at analysts. IBFlash is purpose-built for undergrads across IB, PE, VC, HF, and Consulting.
Does Multiple Expansion offer mock interviews?
No. Multiple Expansion provides written tutorials and Excel templates and advises you to 'practice relentlessly' on your own — there are no mock interviews and no feedback on your answers. IBFlash adds AI-graded spoken mock interviews that score your verbal responses so you know what to fix.
Multiple Expansion vs IBFlash — which should I use?
Use both. Multiple Expansion is a free, deep resource for learning LBO and paper-LBO modeling in Excel. IBFlash complements it with AI-graded spoken mock interviews, adaptive weakness-engine flashcards, progress tracking, and coverage of all five recruiting tracks — the practice-and-feedback layer a static blog can't provide. IBFlash starts at $40/mo with a 7-day trial.
Why pay for IBFlash if Multiple Expansion is free?
Because they do different jobs. Multiple Expansion is free reading and templates; it can't tell you whether your spoken answers are good. IBFlash gives you graded mock interviews, adaptive flashcards that target your specific weaknesses, and structured prep across IB/PE/VC/HF/Consulting — with a 7-day trial so you can test it before paying $40/mo.
