Replying to First Year Skiing NEED HELP

Hey so i started skiing this year and so far ive gone twice.. (they've only been open twice so far this season) but i want to know what i should be focusing on and what i should put my mind to the most. I pretty much have all fundamentals of riding down and i can slide right foot forward, and right foot forward to switch on a tube... What should i work on next? Left foot forward? swaps? Switch on? i normally think about how to do the tricks all week while im in school but im not sure what to focus on, let me know what you guys think. Im really trying to get good my first year, Fully Committed
