I purchased 7 coruses from Udemy to go deep in python,R and AI.

Could someone help me to say where should i start, then pass and what should i take last and if i have to return one this courses for a refound by redundant information? please.I was in a bootcamp of web programming in python and i learned python but that was months ago. I want to re-learn python and go deep in AI, to find a good work in that and get well paid
