• Full Motion Video
  All courses feature full-motion videos of instructors teaching the information as if they are speaking directly to you. Our unique delivery simulates a one-on-one classroom environment creating a more personal lesson and learning experience.
• Study Guides
  Printable study guides for the entire course are available. This allows all material to be viewed, reviewed, and printed for viewing at a later date.
• Review Exercises
  Each section has a review quiz to aid in the learning process by validating the comprehension of the material covered before moving on to a new section.
• Resume
  All courses are resumed to where you left off last session allowing you to learn when it is convenient for you without the hassle of remembering where you where.
• Live Demonstrations
  Demonstrations are a way for the instructor to show and tell the user how to perform a task by actually doing it on screen in front of them. In this format it gives the user the power to see things done by a professional in the intended environment as many times as they would like.
• Certificate of Completion
  Our training is recognized worldwide for its technology-based IT training curriculums. Upon successful completion of our program, you will be receiving an official Distance Education Certificate of Completion.
