Learning TIA Portal

So, I am entering a competition based around automation and TIA Portal.

Although I am having lessons, I would also really like some extra media on the side, although I do have a manual but when you sit down to read hundreds of pages of not exactly entertaining text it starts to just wash over. 

So my question is do you know of any online videos or other forms of educating myself on TIA portal. 

Also any advise you can offer me would be great

Thank you
