r/artificial - Looking for some advice!

I'm currently on vacation after completing my 1st year of computer science and i wanted to get into Artificial Intelligence (mainly with neural nets) but i was overwhelmed with the information there is online. Which is the best way for me to fully comprehend AI and learn how to apply it in real situations, for example coding an AI to pratice playing chess or some other simple game? Should i do online courses? Any help is much appreciated, thanks!
