HP.com offers free, instructor-led, online business, technology and IT online classes, and quick lessons; all available 24/7.
The HP Learning Center classes (with 2 to 6 lessons) are easy to follow, learners can pick up pointers on how to go about with a digital lifestyle. Ideal for CPD; I've enjoyed the classes I've completed.
Users need to do a free registration before they pick a class to start off.
Classes include two to six lessons and may also include interactive demos, quizzes and assignments.
For quick sessions check out the 5-minute how-to videos or short lessons.
