  1. I was looking for an online course for Six Sigma as my new boss is a true believer and I wanted to have a better handle of what is Six Sigma. I started looking around and found ITU, and bought the course, and could not be happier. I have no intention of getting certified, but at least now I can speak the jargon and understand what my boss is talking about.

  2. The educators at ituonline.com are highly skilled but could improve their methods of instruction. In the CCNA 200-301 course, there’s a heavy emphasis on oral lectures, and it would be beneficial to include more in-depth visual aids. Annotating labs and graphics could also make the educational journey more effective. On the other hand, the N10-008 course instructor consistently offers top-notch material.

  3. The CompTIA PenTest was an excellent course and the instructor, Chrys, explained the material in a clear and easy way for me to understand and comprehend essential techniques. Highly recommend!

  4. This course is super detailed but not boring, and they give you cool projects to actually practice what you’re learning.
