Don't mess around trying to grease an aircraft on to the ground when conditions are against you. By all means go for it on a nice clear day with a bit of headwind - it's good for morale and stops your brain from repeatedly impacting your skull, shortening the evening's beer session with your pals.
If you float on a crosswind landing the aircraft is only going to go one way... downwind. You put a bit of aileron in to stop that happening or land wing-down, perhaps on one wheel.... the longer you are in the flare the more aileron you have to put in.
You'll get away with it in a PA28 / C172 etc. You won't get away with it in a King Air, a Dash-8, a 737 or an A330. You'll scrape a pod, drop one of the wheels onto the grass or scare the hell out of your captain as you blow the spoilers if you don't manage either of the previous. If you're on a commercial course, start thinking commercially. Land it. Put the wheels on the runway at the point you aimed at... do not accept halfway down the runway or on one side of the centreline. Finesse will come later.
Firmly plant your aircraft on the tdz. Get that nosewheel down and remember it's not over until you've turned the engine(s) off. Flying club 'greaser' heroics have no place in commercial aviation, especially when it's gusty or wet.
Some aspects of light aviation differ from the big jets and turboprops - regardless of the wind conditions, you will almost certainly be using full landing flap in an airliner, which would be a a little pointless (and adding hard work for yourself !)in a 4-seater - but some things don't change. I'll say it again.. LAND IT !
My own humble recommendation is get into practice now - it'll be a lot easier when you get that first job
