The CaseTools App Learning Structure

We also asked ourselves the same question. So we spent a lot of time thinking about how to craft the most crucial facts into an easily digestible app that allows you to learn in a flexible manner, feel more prepared, save you time. In addition to that, we also strived to help you to practice your learned skills.

Let me introduce you to the structure of our CaseTools app.

The app is structured in a Learning and Practice path.

🎓 Learning Path


Here you will learn everything about the interview. Discover the various interview structures and get important tips and tricks for the case study, mental math, and brainteasers. It will teach you about how to structure your preparation time, how to approach the case study as well as interesting math strategies to significantly improve your mental math game. We have gathered 20+ commonly asked interview questions and developed detailed answers for them. Furthermore, you can even save your own answers which makes it perfect for practicing and iterating over the best possible answers.

Interview Section


Business frameworks will help you with organizing your thoughts during the case interview. We picked the best and most commonly used ones and created beautiful graphics and detailed descriptions. We currently feature more than 8+ Business Frameworks including the BCG Matrix, Porter’s Five Forces, and the Ansoff Matrix.

Frameworks Section


We believe that getting used to commonly used terms applied in consulting firms will help you impress your next interviewer and significantly help you to stand out from other candidates. This is why we gathered more than 60+ terms in our glossary for you to learn and adapt.

Glossary Section


Facts? Yes, facts. Possessing general knowledge is indispensable especially for market sizing cases (aka. guesstimates). In a case interview, you must be familiar with data about population, life expectancy, GDP…, especially for the country you are interviewing for and popular countries such as the US where most big consulting firms are based. This knowledge demonstrates that you have the potential to be business savvy and are well-read. CaseTools provides you an exhaustive list of 50+ countries with facts about economy, society, and geography so that you will easily master those guesstimates.

🧠 Practicing Path

Mental & Business Math

During the case interview, your quantitative skills will be also put to the test. Typically you are not allowed to use a calculator — hence being proficient in mental math is essential for your interview success! ⁠CaseTools helps you to enhance your mental maths skills with addition, subtraction, division, multiplication, and percentage calculations. ⁠You can even adjust the difficulty level ranging from easy to hard. ⁠

Similar to mental math, you will also need to show off math skills in a business-related context. Therefore, we have more than 15+ business context math drills for you to practice.

Case Studies

The case study is the heart of the consulting interview. Currently, we have four detailed 20min+ real-life consulting interview case studies that you can go through in an interactive dialog-like controllable flow. This way it will feel like you are experiencing the interview in the first person.
