Many successful candidates who have come to class already possessing substantial skills and knowledge have reported that the class made a positive difference for them.
While attending Red Hat classes can be an important part of one's preparation to take this exam, attending class does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.
