"I am a well-organized student and have devised a plan that works very well for me. When I prepare for an exam, I map out the content I need to learn and divide that content over the number of days I have available to prepare. When I create a study calendar, I leave the final three days leading up to the exam to review the entire library of content. I am a big fan of study aids, as I believe they work much better than simply reading and re-reading the materials. Aids such as flashcards are much more helpful to me than highlighting my notes. I also create practice problems and, when possible, will pair up with a fellow student to test each other in written form or verbal lightning rounds. My approach has been successful, as reflected in my overall GPA."

There is no incorrect answer unless you do not have a systematic method to study for exams. The interviewers want to choose candidates who have proven study methods and who will be diligent students.
