The Wharton Casebook 2024-25: all 18 cases, and how to practice them out loud
The Wharton Consulting Club casebook for 2024-25 is 280 pages with 18 practice cases, and it labels each one more usefully than most books do: interviewer-led or interviewee-led, a difficulty, an industry, and the one skill the case stretches, whether that is structuring, exhibit analysis, brainstorming, case math or market sizing.
This page is an index of those 18 cases with the club's own labels, plus the nine you can run with an AI interviewer today. The prompts, exhibits and answers stay in the book.

What is in the Wharton 2024-25 casebook
- 18 cases
- Each tagged with format, case type, difficulty, industry and a stretch area. Several are marked as McKinsey-inspired or BCG-inspired.
- Drills before cases
- Math analysis drills, structuring drills and chart drills, about 55 pages in total.
- Frameworks and tips
- Sample frameworks by case type, case interview tips, behavioral interview tips and a sample case log.
- A recruiting calendar
- When club events, firm briefings, applications and interviews fall from September to February.
- Other recommended cases
- Nine classics from older Wharton, Kellogg and Fuqua books that the authors suggest you also practice.
The book's own rule of thumb is that most candidates spend 60 to 80 hours preparing. It also gives a time budget for one case of about 20 to 25 minutes: a few minutes to set up, four or five for the framework, three to five building the solution, eight to ten on exhibits and math, and two or three for the recommendation.
It groups firms by the format their interviews usually follow, as a generalization from candidate experience: McKinsey, Accenture and Oliver Wyman lean interviewer-led; Bain, BCG, Deloitte, L.E.K. and PwC lean interviewee-led, and Strategy& appears in both columns. Twelve of its 18 cases are written interviewee-led, so if your first rounds are at McKinsey, the interviewer-led ones (Happy Bellies, PSU Bank Co., Coolant Co., Thomas the Tank, Timeless Comfort, University Program) are the closest match.
Five cases to start with
Roughly easy to hard, using the casebook's own difficulty labels. The ones marked live run tonight with an AI interviewer; the others need a partner or a case you build yourself.
- 1 Run live →
Fruit Drink Co.
Rated easy. One per-unit cost exhibit and a cost-driver brainstorm, a good first rep.
- 2 Run live →
Electro Chargers
Medium, and its stretch area is structuring. A city choice plus a fixed investment estimate.
- 3 Run live →
Coolant Co.
Medium and interviewer-led. A payback comparison of direct entry against a partnership.
- 4 Run live →
PSU Bank Co.
Hard and interviewer-led. Three exhibits and two brainstorms, closest to a long McKinsey round.
- 5 Run live →
Lux Rides
Hard. A landed-cost exhibit where one footnote decides the answer. We walk through it in our MBB prep guide.

Practicing Wharton 2024-25 cases out loud
A casebook shows you the exhibit next to the answer. A live case does not, and that is the whole difference. The 9 cases marked live above run as voice interviews: the interviewer gives the prompt, answers your clarifying questions from the casebook's own information, puts each exhibit on your screen when the case reaches it, waits while you do the math, and pushes back on your recommendation with something you said.
The report compares your numbers with the casebook's answer key and scores structure, math, judgment and communication. Every live case runs interviewer-led, even where a book writes it interviewee-led, so for candidate-led drills a partner who makes you ask for each piece of data is still the better rep.
The rest of the book
For the 9 cases marked "Build it", the open-source case-interview-builder skill turns the casebook pages into the same kind of live case: an exhibit deck, an interviewer-led script with the answer key hidden from you, a weighted rubric and a study guide. It runs in Claude Code, Codex, Cursor and other agents with the Tough Tongue MCP server.
Or run them the classic way with a partner, swapping interviewer and candidate. Giving a case teaches you almost as much as taking one, because you see how much of the score is decided by the first two minutes.

Frequently asked questions
How many cases are in the Wharton 2024-25 casebook?
18, numbered from Electro Chargers (case 1) to Voter Turnout (case 18). The 280-page book also has math, structuring and chart drills, sample frameworks, behavioral interview tips and a list of nine recommended cases from older casebooks.
Where can I find the Wharton casebook PDF?
The Wharton Consulting Club writes it for its members, and copies circulate among MBA consulting clubs and prep communities. We do not host it. Your own school's consulting club is the best place to ask. Cases 1 to 9 can be practiced on Tough Tongue AI without the PDF.
Which Wharton cases are interviewer-led?
Six of the 18 are marked interviewer-led in the 2024-25 book: Happy Bellies, PSU Bank Co., Coolant Co., Thomas the Tank, Timeless Comfort and University Program. The other 12 are interviewee-led. The Tough Tongue AI versions of cases 1 to 9 all run interviewer-led, which suits McKinsey-style preparation.
How long should a Wharton casebook case take?
The book budgets about 20 to 25 minutes for one case: two or three minutes to set up and recap, four or five for the framework, three to five building the solution, eight to ten on exhibits and math, and two or three for the recommendation. Full first rounds with fit questions run longer.
Can I practice Wharton casebook cases with an AI interviewer?
Yes. 9 of its cases run on Tough Tongue AI as voice interviews: the interviewer gives you the prompt, puts each exhibit on your screen when the case reaches it, waits while you do the math, pushes back on your recommendation, and grades you against the case's own answer key. For any other case in the book, the open-source case-interview-builder skill turns the casebook pages into an interviewer-led case with a hidden answer key, run from Claude, ChatGPT, Codex or Cursor.
