Pls friends, I actually know html and css. Currently, am doing web development, but the school is not competent at all. I want to augment my training there with an online quality free or paid video tutorials on php and javascript.

I stumbled on udemy.com, but they said their videos are not downloadable. That one must have to be online to watch them. But i want to download and watch offline to reduce cost of internet connection.

I know about lynda.com and tutsplus.com, but i don't know how competent they are. I want a comprehensive and in-depth training in web development.

Pls can anyone recommend me any free and paid QUALITY video tutorials online?

Thank u.
