If you insist on using an online tutorial, or don't have the $20-40 for a non-credit class, then I'd say, go with it, and if you can't seem to understand, go to a class, non-credit classes are usually 4-7 days, that is enough time to get you familiar with the equipment, their names, uses, slangs, etc. And how electronic devices work, after that you can move up, and take another class and learn how to build a few things.
They're great, I got to build a blinking LED array, a basic AM radio, a nightlight, and a few other things I can't really remember.
