The main advantage of instructor-led training is that the student gets to interact with the instructor, ask questions, and ask for further explanation when things are not clear. Classes also offer a more structured environment; they meet on a certain schedule with assignments due to each class. Many people find it easier to learn new technologies in this type of environment compared to trying to learn them themselves. Another big advantage of instructor-led training is the opportunity to interact with other students that are in the same position you are. Many students say they learned as much from interacting and working with the other students in the class as they did from the instructor (it’s also a great place to network).
