Man do not waste your time to learn JQuery.
In fact the sooner that JQuery dies, the better for the World :)
I discovered Coursera a while back. You can take all kinds of classes (and tons of computer related ones), for free, and they are very good. Universities from all over the world participate in hosting these classes. Most of them take 68 weeks to complete, and you do it at your own pace and time. Here's the link: https://www.coursera.org/
Most of the sites that I see using jQuery tend to be bloated messes filled with errors, and often will not even display pages properly on any but the coders' computer. For example, I visited one site today using jQuery (a government site) and the pages won't even load because they are stuck in an endless jQuery loop.
