Everybody learns in a different way, so I can't really give advise..
I myself learned (and still learn) by reading a lot in this How do I section, also topics that have nothing to do with what I'm working on..
Lots of trial and error and searching for solutions on the forums, putting events together from different things I read..
Other people learn best by looking through tutorials and this site has a lot..
Also there are many on youtube..
And others again learn from dissecting capx's made by other people..
This forum, the examples shipped with construct and the capx tutorialsection is a good place to start for them..
