Everyone in IB recruiting reads Wall Street Oasis. The forum has been the center of gravity for finance careers since 2006, it is free, and nothing on this page suggests you stop using it. But when candidates compare Superday AI against WSO, the forum is not actually the choice on the table. The choice is whether to pay for WSO's prep products: the interview prep course, the financial modeling package, mentor sessions billed by the hour, and WSO Academy, the application-based program reported to run $6,000 to $9,000.
Those products share one design: content you read and humans you book. The courses are static question guides and videos. Feedback on your actual answers means paying a mentor per hour or getting accepted into Academy. Superday AI is built the opposite way: one subscription where practice is the product, every answer gets graded by AI against banker-written rubrics, and mock interviews adapt to you, with nothing billed by the hour.
So this page compares the things that cost money: what WSO's paid prep includes, what Superday AI includes, what each costs as of July 2026, and who should pick which. We build Superday AI, so read the WSO praise below as exactly what it is: things they genuinely do better than anyone, including us.
