the way the trainer used to explain by drawing diagrams and not just going through the slides and reading from it.
Ibrahim Ghassal - Saudi Airlines
Course - CompTIA Network +
The trainer was extremely knowledgable and helpful. While walking through the exercises, I wasn't rushed and was allowed to make mistakes (to a point) and then help was given to correct to them where needed.
