I am developing a sense of practical application by listening to the lectures and watching the "Noraengi" (Yellow Book) problem-solving videos. As a non-major, I still have a long way to go, but I plan to take the exam by repeatedly reviewing the problem-solving sessions. The lecture materials provided are very helpful; in particular, running the practice queries myself has helped my memory, and being able to change various elements to deepen my understanding has been great.
