Inside the GMAT
Data Insights gives you a lot to look at, but that doesn’t mean you need to understand all of it.

In this episode of Inside the GMAT, GMAC Zach sits down with Dr. Rodrigo Tello, MBA Program Manager at Oklahoma State University and a researcher studying chronobiology and circadian rhythms in organizational management.

Key Takeaways
- Official questions matter because they are real GMAT questions. Third-party prep can teach concepts and strategies, but official GMAT questions are the best way to practice what the real exam will feel like.
- The Official Guide works best after foundational learning. Candidates should first learn the underlying content, question types, and strategies, then use the Official Guide to quiz themselves.
- Review is where score improvement happens. Stacey emphasizes that every question should be reviewed, including questions answered correctly, because correct answers can reveal shortcuts, traps, and repeatable strategies.
- Mixed practice is more effective than over-drilling one question type. The GMAT requires candidates to shift between skills, formats, and sections. Prep should mimic that experience.
- The newest Official Guide may be worth it, but not always immediately. If a candidate already owns last year’s guide and still has plenty of unused questions, they can continue with it. If they are buying for the first time, the newest edition is the better choice.
- Practice exams should be used carefully. Candidates should review each practice exam thoroughly and complete targeted study before taking another one.
