Almost every candidate starts in one of these places:
Each serves a different purpose. The real question isn't which one teaches finance best — it's which one actually helps you perform when an interviewer is sitting across from you.
Books remain a popular starting point because they're inexpensive and comprehensive — interview guides, accounting primers, and technical question banks are all easy to find.
What they're good for: low cost, solid coverage of fundamentals, and something you can flip back through anytime.
Where they fall short: books are entirely passive. Reading a definition of enterprise value five times can feel like mastery — until an interviewer asks "why do we subtract cash when calculating enterprise value?" and you're suddenly reconstructing the logic instead of reasoning through it out loud. A book can't tell you whether your explanation actually makes sense, ask a follow-up, or catch weak communication. Interviews aren't open-book exams.
Courses combine video lessons, quizzes, and a structured curriculum — usually covering accounting, valuation, DCF modeling, M&A, and resume advice. If you're learning finance from scratch, that structure genuinely helps.
What they're good for: logical progression through concepts, and better visual explanations than piecing things together from scattered videos.
Where they fall short: most courses stop once they've taught the material. Learning isn't the same as interviewing. You can spend 40 hours on valuation lessons and still freeze when an interviewer interrupts your DCF walkthrough mid-sentence to ask what happens if WACC increases by 2%. Videos don't prepare you for that moment, and most courses offer little to no feedback on how you actually sound answering out loud.
ApexIB approaches this differently. Instead of asking "have you watched the lesson?", it asks "can you answer the question?" — a distinction that matters more than it sounds.
Investment banking interviews are verbal. Success comes down to organizing your thoughts quickly, explaining concepts clearly, handling follow-ups, and recovering smoothly from mistakes. Those are skills, and skills improve through repetition — not reading. Ask someone to "walk me through a DCF": a book gives you the answer, a course explains the answer, and ApexIB asks you the question directly, grades your response, flags what's missing, and lets you retry until the explanation is natural. That's much closer to what an actual interview feels like.

Many students spend weeks consuming content — finishing a whole course, reading two interview books, taking hundreds of notes — before ever trying a mock interview. That's usually the first moment they realize knowing something isn't the same as explaining it out loud. A candidate who spends 15 focused hours actually answering interview questions will typically outperform someone who spent 50 hours watching videos. Interview performance comes from practice, not just knowledge.
Books are valuable references. Courses are useful teachers. Neither recreates the experience you're actually preparing for. If your only goal is learning accounting or valuation, a book or course may be enough on its own. If your goal is an investment banking offer, at some point you need to practice interviewing — that's the gap ApexIB is built to fill, and it works well alongside books or courses you've already started.
