hi!

Yes! For chart interpretation and math drills, I recommend:

  1. The Case Math Tool here on Prep: great for mental math and quick calculations
  2. Victor Cheng’s Case Interview Math: simple but very focused
  3. GMAT Data Sufficiency/Interpretation: especially helpful for chart reading under time pressure
  4. Case books (e.g. Wharton, Kellogg) often have math-heavy exhibits to practice with

Try to time yourself while solving to build speed too!

Happy to share more if needed!

Best,
Alessa :)

Hi there,

As you’ve already received some good resource suggestions, I’ll add one quick tip: Most strong candidates can understand a chart. What separates the great ones is knowing exactly how to take in the information, discuss it with the interviewer, concisely share the key insights, and link it back to the overall hypothesis.

The best way to build this skill is by practicing charts and math live — ideally with other advanced candidates or a coach who knows the exact techniques and can give targeted feedback.

Feel free to reach out if you’re interested in a free call to explore what such a training could look like.

Cheers,

Kevin

Case books are full of them. 

You can even ask ChatGPT to provide some.

But the most important thing is to have the technique right, not to just do lots of practice.
