How to prepare for the Korean Language Proficiency Test (TOPIK)

This is my first time asking a question. My daughter wants to attend a foreign language university in Korea, and I understand that she needs to score well on the Korean Language Proficiency Test (TOPIK) as an admission requirement. I would like to know specifically which level is required, and what kind of study methods are effective for preparing for the exam. I would also appreciate any advice on the process in Korea, such as the exam format and testing centers. As a parent, I would like to know if there is anything I can do to support her.
