For both the instructor and dropzone. Each student comes in more prepared. Instructor can personalize and tailer the classes based on what the student has shown to understand online.
Make it easier for students to schedule themselves to be in for subsequent jumps. Have instructors ready and fewer students arriving unexpectingly.
Cut down on in-class time. This means more in-air time for both the students and the instructors from Day 1.
Help ensure that every student is being taught all the same information with consistency, regardless of who is teaching the in-class.
